Imagine that a mutation in a DNA molecule results in the codon CCU being changed to CCC. Both of these codons code for proline. The fact that more than one codon can code for the same amino acid is referred to as
A) the ambiguity of the genetic code.
B) the redundancy of the genetic code.
C) the universality of the genetic code.
D) mutations in the genetic code.

Question

Quizplus · Accepted Answer

The fact that more than one codon can code for the same amino acid is referred to as the redundancy of the genetic code. Option A is incorrect because the genetic code is not ambiguous, as each codon codes for a specific amino acid or stop signal. Option C is incorrect because the universality of the genetic code refers to the fact that the same genetic code is used by all living organisms. Option D is incorrect since mutations refer to changes in the sequence of genetic material, not to the normal function of the genetic code.
