Question

Quizplus · Accepted Answer

The genetic code uses a sequence of three nucleotides in mRNA, known as a codon, to code for a specific amino acid. Therefore, the genetic code is said to be triplet. Choice A is incorrect because there is only one amino acid per codon. Choice C is incorrect because there are only three codons that signal termination of translation. Choice D is incorrect because "nonsense" triplets, or stop codons, do not code for amino acids.
