DNA participates in protein synthesis through
A) cyclic messengers.
B) direct pairing with amino acids.
C) an RNA intermediate.
D) protein folding.

Question

Quizplus · Accepted Answer

DNA participates in protein synthesis by serving as a template for the synthesis of messenger RNA (mRNA), which carries the genetic information to the ribosomes where it is translated into a polypeptide chain. This process is referred to as transcription and it involves the synthesis of an RNA intermediate (mRNA) that is complementary to one of the DNA strands. Once the mRNA is produced, it travels to the ribosomes where it is read by transfer RNA (tRNA) and translated into the correct sequence of amino acids to form a protein. Therefore, the correct answer is C - an RNA intermediate.
