If you are asking if it is a true or false statement, it is a false statement. A mutation cannot possibly occur during polypeptide production or any protein synthesis or process. However, mutation may occur if the protein or enzyme is involved in any DNA replication or transcription process.
From DNA to RNA, purines and pirimidines transform in this matter:
(A) adenine => (U) uracile ; because RNA has uracile instead of timine in DNA
(G) guanine => (C) citosine
mRNA: G U G C A C C U G A C U C C U G A G G A G
GUG-valine
CAC-histidine
CUG-leucine
ACU-threonine
CCU-proline
GAG-glutamic acid
GAG-glutamic acid
