Question

Given the coding strand DNA sequence below, what change would occur in the expressed protein sequence if a mutation resulted in the insertion of 'G' prior to the first nucleotide: 5'-AATGCCGTAA-3'? a) The amino acid sequence would remain the same. b) A frame shift mutation would occur. c) A new stop codon would be introduced. d) The protein would become shorter.

Answer 1

The insertion or deletion of a nucleotide sequence is also known as a frame shift, therefore the answer would be B
