can somebody tell me the functions of
1.DNA
2.RNA
3.mRNA
4.tRNA

[canalon]

Your textbook?
Our dictionnary?
Our genetics tutorial?

You should start by looking up by yourself. And come here for more detailed questions.

For DNA: http://en.wikipedia.org/wiki/DNA

For RNA: http://en.wikipedia.org/wiki/RNA

For mRNA: http://en.wikipedia.org/wiki/Pre-mRNA

For tRNA: http://en.wikipedia.org/wiki/TRNA


Just a tip: It's always better to check out the info yourself first before asking others. Make it a habit to check and learn from it. Use the dictionary, tutorial present in here or you can use http://en.wikipedia.org/wiki/Main_Page

But this time I have checked out the info for you.

I have read many threads on this site, most of which are highly informative, however, a few months back I came across a web site that gave out some startling information on the evolution of mankind, and can I find it again...not without some help.

It went along the standard lines of the formation of the sun, and the solar system that span out from this, proven by experiments, and observations of the galaxy. Thus formed the Earth and surrounding planetary solar system, nothing unusual there.

It then went on to discuss the formation of RNA (plant DNA) from bacteria found even today on asteroids that would have piled into the Earth, billions of years ago, no probs there, however it was adamant that DNA (Human/animal) could never have evolved by this system, and could only have been introduced to the Earth from human DNA on an aseroid, or other means from another planetary system,(Alien?) thus proving life beyond our solar system. It also states that several puzzling facts have come to light , such as the discovery of a footprint, with a stitched sole, within the strata of rock, 250 million years old, some basic cooking implements, and some marble type objects. The theory, at least on our present form is that humans were living on this planet millions of years before present mankind, the Earth surface then melted down and reformed, thus wiping out all forms of life. The RNA and DNA were in existence already as this cannot be destroyed even by nuclear means, and so evolution began again, by the combination of hydrogen, oxygen and a few other gases combining with the bacteria molecules, and here we are now. We didn't spring up from monkeys, although undoubtedly we have evolved, as have most forms of life.

Could of course be a load of old rubbish, but it does raise thoughts.

I feel very glad in side me when new people starts answering and discussing fact that are posted by new members and repeated for "Old members"..

After reading their answer we can just quote and correct them with discusssion...

In order to disprove the generally accepted scientific theory, one must provide an immense amount of evidence, which they failed to do..

Ya this is one of those thories of organic evolution....(most accepted)

Of course MrMistery, and thank you sachin, however, check out this site, it is most interesting.

"I feel that the effect of hypotheses of common ancestry in systematics has not been merely boring, not just a lack of knowledge; I think it has been positively anti-knowledge . . Well, what about evolution? It certainly has the function of knowledge but does it convey any? Well, we are back to the question I have been putting to people, 'Is there one thing you can tell me about evolution?' The absence of answers seems to suggest that it is true, evolution does not convey any knowledge." —*Colin Patterson, Address at the American Museum of Natural History (November 5, 1981).

Looks like quote by any non science person....

[Dustfinger]

Exactly. Scientifically it DOES convey knowledge.

[MrMistery]

i stopped bringing counterarguments to creationists a long time ago. it's something that people must simply agree to disagree.
but i wonder why that thing compares humans to gorillas and not to Robustus, Erectus, Australopitecus, Habilis etc. Also, it states that there is a huge difference in DNA- yeah, 2%. really big. and in the non-coding part mostly. also, it calls differences between the cranial capacity of humans and apes. well, our big brain is what tells us appart from them, of course it is different.
and so on, so forth..

wow............ MM you r going right way.........
