Which of the following descriptions of nucleotide triplets best represents a codon?

Question

Quizplus · Accepted Answer

A codon is a nucleotide triplet that codes for a specific amino acid. It is located in the same reading frame as an upstream AUG, which serves as the start codon for translation. This is important because it ensures that the ribosome begins translating the mRNA at the correct location and in the correct way. Choice A is incorrect because triplets can be adjacent to each other in the same reading frame. Choice B is incorrect because all codons correspond to at least one amino acid. Choice C is incorrect because tRNA anticodons, not codons, are located at the opposite end from the amino acid attachment site. Choice E is incorrect because the 3' end of tRNA contains the amino acid attachment site, not codons.
