By: ddrjakkl. on 30 Jul 10, 08:50:30
@HACKERNOH8R U claim that billions upon trillions of years couldn't make something this remarkable, but think that you can sum up what did in one word?God? The world is changing fast and God is not looking omnipotent lately because He can't catch up.If poetry be damned then there would be almost as little connection between God and what we now know about DNA as there is between DNA and any other part of history.

@sacr3 here is a great verse to meditate on: Isaiah 40:12 (New International Version) 12 Who has measured the waters in the hollow of his hand, or with the breadth of his hand marked off the heavens?

By: muktuklou. on 29 Jul 10, 16:23:53
@sacr3 I do not claim to understand God in His entirety. We humans were graced with the knowledge of God (that He gave us about Him) By His Word- The Bible- My 30 years of reading and studying the Bible (besideds experiences) has proved to me that the Bible is the Word of God. The Biblical prophesies, accuracy, no contradictions and Extra Biblical evidences and Miricales throughout history speaks for itself. Psalm 19"The heavens declare the glory of God"

"Throne" you really think something as powerful as it is would have a throne? I don't know about you, but something powerful enough to create 4 laws and have a masssssssive universe like this, with quadrillions of stars/planets all working, down to the atom.. I don't think it has the logic of a human being

God has a nasty sense of humor. From ?Little Bessie? by Mark Twain "That Hollister is a scandalous person, and I don't want you to listen to anything he says." "Why, mamma, he is very interesting, and I think he tries to be good. He says the wasps catch spiders and cram them down into their nests in the ground -- alive, mamma! -- and there they live and suffer days and days and days, and the hungry little wasps chewing their legs and gnawing into their bellies all the time, to make them good

By: beeecraft. on 27 Jul 09, 04:59:51
I believe that the positive charged Na ions bind to the negatively charged phosphate backbone of the DNA molecule, causing an opening of the secondary (and tertiary) structure. The atoms force open the molecule through steric hindrance, similar as to why all molecules have defined angles and shape. Also, they prevent the binding of positively charged histone proteins that help wind the DNA.

It uses mRNA so the actual DNA doens't have to leave the nucleus. If it had to it would have been in greater danger of mutation. It for the protection of the DNA itself.

By: jrpestana. on 23 Feb 10, 07:11:12
The mRNA has become the template. Remember, the DNA does not leave the nucleus. The mRNA leaves the nucleus in the direction of a ribosome where it can be "translated." This creates a tRNA (transfer RNA).

@TheFanOfCrypto138 It is not easy for people to let go of beliefs that they have held for so long. I accept evolution, it is a fact and not a beliefe as you say. Evolution is consistent like gravity and will continue to exist even if we forget all about. People who reject evolution will grow to accept it when they are ready, we cannot force it down their throat. That is what seperates scientists from fundamentalists.

we didn't evolve from monkeys, we share a common ancestor with chimps. There are more than a dozen fossil species that show transition between humans and other apes. A good example is australopithecus, basically an ape that could run on its hind legs. You can look the rest up on wikipedia

By: 4thachange. on 16 May 10, 21:44:44
There also are no fossils to prove that we evolved from monkeys.. This idea is simply far-fetched.. and the truth of the matter is... we should NOT believe what is told to us by anyone. We can only try to come to a Logical and Rational stand point. The God we 'know' from the Christian bible is also not True.. not saying that God does not Exist. Just saying that the Bible has been tampered with. Do not believe the Bible Either. There are people in the world which shield us from the Truth.

By: 4thachange. on 16 May 10, 21:39:41
it IS True that we see Micro-evolution.. mutations to small creatures and are thus mutated.. these are evolved creatures. Their genotype has been altered and thus their anatomy and physiology resulting in a 'new' creature. We do not see this same thing with Separated Gene Pools-- Different Species. For example-- such as the Myth that humans evolved from Monkeys. There simply is not enough evidence for that.

One must understand the Hebrew word "rib' (Genesis 2), to understand what occurred when Eve was created. The word rib is "tsela" which is from the Hebrew word "tsala" which means to curve. Since DNA was unknown in 1611 therefore the writers of the KJV dismissed the word curve. We all now know DNA as the helix curve. It makes since therefore, that God would have created Eve from Adams DNA "tsala or? curve".

@gopacers305 ---HOO HOO HA HA....We did not evolve from monkeys. Read this carefully. Primates and humans all originated from a common ancestor 6-7 million years ago. Oh! Oh! Thats why 'monkeys' are still here my little pea brain. As far as where did everything come from? Matter? Nobody knows so lets not jump to conclusions on this god guy. I have not met 'him' and neither have you.

@BioGuelph The Elohim are extra-terrestrials scientists who created all life on earth 25000 years ago. We mistook them for "gods". They sent prophets to keep in contact with us. Jesus,Buddha,Moses,Muhammad,etc are all prophets chosen by The Elohim. Now men have reached the age of science, the time has come for The Elohim to choose our final prophet Rael. Using the bible as explanation,The Elohim demystify "god" with science.

By: BioGuelph. on 24 Jun 10, 21:15:50
@gopacers305 This is because you do not understand evolution, we share a common ancestor, we did not "come from them". As to where matter comes from, no one knows, but it's twice as unlikely that a god existed to create it in the first place because that also requires something to exist where there was nothing and for it to create something from nothing. One of the ideas floating around is that causality only existed when matter came to be.

By: gopacers305. on 18 Jun 10, 15:23:26
I know this is off topic from the point of the video but the comments section demands I ask some of the intelligent people who are quite confident that the God of the Bible does not exist: If God didn't create the universe, how did even a single molecule come into existence on its' own? Oh and if we came from monkeys, why are there still monkeys?

How can we rapidly change dogs through selective breeding. Remember that a scientific theory is fact and you are late to the dance. Remember that evolution doesn't mean there is no god, it just means a book written 2000 years ago wasn't accurate...imagine that

By: Phyerbyrd. on 27 Feb 10, 09:18:03
Things don't just deteriorate. Life is capable of homeostasis and is not affected by entropy. Evolution is actually very effective. Those creatures died because they couldn't evolve fast enough. They didn't die because of deterioration, but because they were an earlier model of what was to come. The Y chromosome won't disappear, we would die off if it did, and individuals that have faulty genetics can't spread on bad genes.

By: Dirge987. on 24 Feb 10, 04:38:48
Silex, Humans are not perfectly designed in the least. I prefer to think that we are still in the process of change. Humans aren't the finished product, only a intermediary. In reality, our teeth are too big for our mouths. Our eyes have blind spots where the optic nerve connects. Sexual organs are located where we expel waste. Intestines get tangled from standing upright. Did a god make an imperfect product, or do we just have remnants from our evolutionary past? Which is more likely?

Even if the chances ...
By: keep6rocks. on 22 Feb 10, 04:47:11
Even if the chances were 1 in a 100000000000, there are at least that many galaxies, with at least that many stars in those galaxies for at least that that many years. I find it far more likely to find life than not in a universe where the laws of nature permit such an occurance. P.S. if you actually went out of your way to learn about evolution I think you will find it quite beautiful, simple and obvious.

I'm not a physicist and won't go into a discussion on the big bang, but your comment suggests that "god" is simpy to label things you don't know. The word "god" is conviently very flexible in meaning. "You believe that it is inevidable for us to create wars and kill one another. You killed the wonder of the world. I am in awe of the beauty that God designed. My simple question for you is, why?" Was that question directed to me?

Since no one has answered you: It's DNA Replication. Copying DNA into two identical strands. DNA transcription to RNA (and on to Translation into protein) is significantly different. You would see a protein unwinding the DNA as it moved and rewinding it after it had passed. (with another 'string' growing out of it. Same people made an animation of that, don't have the link but should be able to find it somewhere.

So go practice sticking a fork in the toaster while the rest of us puts your 6 thousand year old universe in the fiction section. We used to live on a flat earth, with stars in the sky, our core was hell, and spirits are inside us. Now the earth is a sphere, the stars are in space, our core is lava, and you're full of shit.

As for everybody else; most people love learning and understanding new things. People are curious and generally fascinated by nature, if they haven't been bullied into darkness. Good luck to you too thruthofevolution.

By: marsCubed. on 30 Dec 08, 07:55:52
I think I may have fumbled what I was trying to say. My assertion was that creation makes falsifiable claims, many of which are big time falsified. It is not possible to discuss what colour mountain is, if there is no mountain. Geology, DNA etc all falsify creationism, debating with ID is useless, better to concentrate on educating and enlightening those who are interested and ridiculing the nuts who are not, they just want to recruit into their cults and have nothing to offer biology.

It didn't feel good, I felt awfully lonely, but it felt 'honest'. I don't even smoke weed. Tbh, it's annoying that all the visual illustrations about whatever scientific events are most often illustrated with some sort of a music in the background when shown to the masses.

Survival of the ...
By: stork5100. on 16 Aug 09, 03:23:29
Survival of the fittest. Fittest, not strongest. Sometimes an organism is more fit, not because it is the strongest, but because it is faster, smarter, less visible, requires less food, reproduces faster, or more socially cooperative. Organisms that can cooperate in a society that ensures the survival of all its members are more fit than those who use strength to take whatever they want. A society is well within its rights to censer, punish, or remove a member whose behavior is antisocial.

By: NessTheNoob. on 08 Aug 09, 03:36:07
I know this comment was made 4 weeks ago but the short answer (from what I learned in Biochemistry) about the energy is that the energy comes from the break down of ATP to ADP, releasing energy to make the machines work. The ATP comes from the Krebs cycle, which is in the mitochondria of our cells. The initiating material of the Krebs cycle comes from glycolysis, which is the break down of sugar (glucose) into precursors of many cycles. Our body is amazing.

By: Neurozumim. on 09 Jul 09, 12:43:01
Ok.. I'm impresed. I can't believe we have these millions fast workingh macchines inside of us. What makes them move so fast? Where do they get the energy? From the food we eat, I suppose, but it seems that once a new cell is born it just goes on its own, like it has the energy all encompass within it. Very strange. The blue proteins (are they really blue?) in the beginning look like attacking insects.

By: TheAniaHS. on 18 Jun 09, 12:37:11
polimerase DNA can add new nucleotide only to one end of strand. One strand is opposite to another. These ends are called 3' and 5'. So new nucleotide are added onl to 3' end. The other strand has to be copied "in parts" what means new starter and then adding new nucleotides to 3' ends of starter "backwards".

By: somnolent49. on 08 Jun 09, 09:49:07
If we are merely biological machines, then whining or complaining is based upon that biological machinery. Saying it has no basis is absurd. If you're attempting to say that complaining about the outcome of events in a deterministic universe is ludicrous, then you should say so, but the universe does not appear to be deterministic.

By: porkwood. on 03 Jun 09, 17:36:07
For those who insist that we are only biological machines,please accept without whinning when you are raped,robbed or murdered. You have no basis for complaint. Non exists.Of course we have a society that attempts to live "civilised". But that society also has no basis for complaint when destroyed. Naturally each has the "inbuilt right" to defend itself. Whinning is an irrelevant notion.Survival of the strongest.

By: Josephjoel3. on 27 May 09, 01:32:33
The problem is not about GOD. GOD is irrelevant. The problem is belief. Why have belief, when the movement of life does not care for the petty little structures we create. MAN does not care about LIFE. We care about ways of LIFE. Belief is not necessarry when life is able to autonomously generate itslef regardless of religion, faith, or this non-sensical, non-existent GOD. Refute all belief! It is in direct oppostion to LIFE! Also read up on UG Krishnamurti. It will BLOW YOUR MIND!

By: Onecreationltd. on 05 Jul 10, 03:55:52
@jcshieh vodka works quite well, the chemicals we use in a lab are actually either methanol or ethanol aka 200 proof grain alcohol. Its actually a parlor trick to use vodka or another high proof alcohol. Oh and the cold alcohol question above? first, cold is to help keep the DNA strands together, the SLS (sodium lauryl sulfate) in the detergent is detrimental to the hydrogen bonds in DNA. second, Nucleic acids are actually still soluble in isopropyl alcohol, it however isnt soluble in ethanol.

By: jcshieh. on 19 Jun 10, 00:09:13
@zer0eclipse That's a good question and I'm not sure of the actual answer but I think the cold helps with the precipitation. My guess is that the cold helps keep the DNA from dissolving in the alcohol. Remember the sugar dissolving in water analogy - sugar dissolves in warm/hot water more easily than cold water. Maybe it's a similar principle here.

Nice at home experiment. Why does the alcohol need to be cold though? Are you for some reason worried about degradation?

@giraffeh1 I haven't tried it myself and would expect that it wouldn't work as well (just because the alcohol content of vodka and other spirits tends to be on the low side compared to rubbing alcohol), but I've seen some instructions online using vodka. Try it out! (and let us know)

By: jcshieh. on 18 May 10, 00:51:23
@hashbrown567 It is actually a combination of DNA, RNA and other proteins since the way we do this doesn't really purify the DNA away from other nucleic acids. But, one way you could tell is to use certain chemical reactions that only happen with DNA, or another way is by using a staining dye that sticks to DNA. There are some dyes you can get at a pet shop that are attracted to acids, like DNA and RNA, so you might be able to tell if it's acidic or basic by using this dye.

By: jcshieh. on 19 Apr 10, 16:32:39
@jophi76 You should experiment and find out! The reason we use alcohol is because DNA doesn't dissolve in it, so if DNA can dissolve in hydrogen peroxide, we shouldn't be able to see it when you pour the hydrogen peroxide in. But, I don't know for sure, so why don't you try it and report back?

By: jcshieh. on 19 Apr 10, 16:28:54
@MrFiv3 Yes - other fruits & vegetables would work too but give varying amounts of DNA. Also, some plants are likely to be harder to break down just by squishing so you could try throwing them in a blender. Some other things that might work pretty well: kiwis, bananas, split peas, broccoli, spinach, chicken liver, sweetbread (cow thymus)

Restriction enzymes ...
By: jcshieh. on 09 Jan 10, 20:19:46
Restriction enzymes (or restriction endonucleases) are useful for chopping up DNA into short fragments - like cutting up a word into smaller letter fragments. Those small fragments can then be compared using gel electrophoresis. You're probably thinking of a Southern blot, which can be used to test the identity of the actual sequences contained in those fragments (like, is it ACGT or GCTA). A northern blot is very similar but used for RNA.
