A RNA Code for the amino acid lysine

Post by faith1726 » Thu Apr 12, 2007 8:49 pm

A possible RNA code for the amino acid lysine?

Would a code be AAA or AAG

And for RNA code for the amino acid methionine?

would one be: UUU

Do these sound correct?

Also....Where can I find the sequence according to the flow of information or sequence of action?????

RNA, DNA, Physical trait & Chemical reaction

You are right for the code for lysin,but AUG is for met.UUU stands for phe.

Go there (and probably any other biology, biochemistry or genetics textbook) and you can find the codons for all the amino acids.

As to the flow of information, it sounds like you're referring to Crick's famous "Central Dogma" of molecular biology that "DNA makes RNA makes Protein" only you've added "chemical reaction" and "physical trait" to the system. Since the trait will be determined by the protein (to oversimplify), the physical trait has to be the "destination" of the pathway. I would argue that chemical reactions are part of all the steps, so if it were my dogma, it wouldn't be there. If you make me put it in the pathway somewhere, then I guess I would put it as the first step. So the modified Central Dogma would go:

chemistry makes DNA makes RNA makes Protein makes trait
