A. before the 2nd base
B. after the ribosome initiates a stop codon
C. at the 3rd base
D. when the ribosome falls apart
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 randomness of the genetic code
d.
mutations in the genetic code
