What determines the sequence of amino acids in a protein?
a. primary structure
b. sequence of nucleotides in RNA, which was determined by the sequence of nucleotides in the gene for the protein.
c. sequence of nucleotides in DNA, which was determined by the sequence of nucleotides in RNA
d. the sequence of RNA nucleotides making up the ribosme
e. the 3-d shape of the protein
After looking in my textbook, I found "the precise primary structure is determined not by random linking of amio acids, but by inherited genetic information."
On Wiki, I found nothing of use.
So I think 'a' and 'e' are out.
All the biology jargon is throwing me off as to whether the answer is B, C, or D.
My guess is 'c.'
Thanks!

Oh, of course!
DNA!DNA stores genetic material and RNA takes it to wherever the protein is built. Then the sequence of the nucleotides matters.
It is 'c.'

i am pretty sure that the sequence is determined by the DNA
so in other words it is the DNA choice

Re: What determines the sequence of amino acids in a protein?
You can determine the order of these steps by looking at these terms in Wikipedia:
transcription
translation
transcription
translation
Warning, your options are tricks! That is why (c) is wrong (it's a trick answer!).
Hint - the correct answer is true, but slightly incomplete
Once you've looked up transcription and translation, you'll see why.
A lot of multiple choice questions require realy, really careful reading, or they will catch you out!
Here's a good word for you - co-linear. It means the sequence of amino acids in a polypeptide (subnit of protein) is colinear (ie, the same order) as that of (a) xxx and therefore (b)xxxx (you'll know the words once you've looked up transcription and translation.)
Good luck!
