Question

Quizplus · Accepted Answer

A DNA sequence is translated into an amino acid sequence using the genetic code. The table of the genetic code shows that AAC = Asn, GGT = Gly, CAC = His, CCA = Pro, and CGG = Arg. Putting these amino acids in the correct order gives "Asn-Gly-His-Pro-Arg". Comparing this sequence with the answer choices, only option B matches. Therefore, the correct answer is B: leu-pro-arg-gly-ala.
