A sequence of three bases forms a(n):
A) codon.
B) anticodon.
C) amino acid.
D) polypeptide bond.

Question

Quizplus · Accepted Answer

A sequence of three bases in DNA or mRNA is called a codon, which codes for a specific amino acid or a stop signal during protein synthesis. Choice B is incorrect because anticodons are three bases sequences found on tRNA, which are complementary to the codons on mRNA. Choice C is also incorrect because amino acids are assembled in a polypeptide chain as directed by codons. Choice D is incorrect because polypeptide bonds connect amino acids together during protein synthesis, but they are not formed by sequences of three bases.
