Question

Which nucleic acid provides the master code for protein synthesis?
A. DNA
B. RNA
C. mRNA
D. tRNA

Answer 1

mRNA!

Answer 2

it is the messenger as it feeds information

Answer 3

thank you.

Answer 4

anytime !

Answer 5

sorry if my responses come kind of slow, but my pc is stubborn and these online summer classes are the pain in my knees. I say that because I have tendonitis in both my knees, guess that's what I get for being lazy one summer and getting back to school!

Answer 6

hahaha no problem !

Answer 7

I don't think that is right @rushwr. it says "master code". To me, this means mRNA canot be the answer because mRNA is in fact encoded by something else, thus the "something else" indirectly codes for proteins.

Answer 8

so is it the RNA >? @mrdoldum

Answer 9

I think I have to agree with mrdoldum. It sounds like the answer is DNA.

Answer 10

@Rushwr I think the best answer is DNA. All proteins (I lie), are ultimately encoded by DNA. Now, I say "I lie" because, well, I do. The fact is a recent paper found that there is a way to alter and make proteins somewhat independent of DNA. Somewhat in the sense that all though you won't find anything that could encode for that final protein directly, you will find the "base" protein instruction in the DNA and instructions for the cellular mechanisms that make a unique protein.
