When examining the genetic code,it is apparent that ________.
A) there can be more than one amino acid for a particular codon
B) AUG is a terminating codon
C) there can be more than one codon for a particular amino acid
D) the code is ambiguous in that the same codon can code for two or more amino acids
E) there are 44 stop codons because there are only 20 amino acids

Question

Quizplus · Accepted Answer

There are multiple codons that code for the same amino acid, meaning the genetic code is redundant or degenerate. For example, both GCA and GCU code for the amino acid alanine. However, each codon typically only codes for one amino acid, and there are three codons (UAA, UAG, and UGA) that function as stop codons. There are no stop codons that code for amino acids. Therefore, choices A, B, and D are incorrect. Choice E is also incorrect as there are actually only three stop codons, rather than 44.
