a mutation in which an extra nucleotide base is inserted into a gene that codes for the synthesis of a protein would cause?


A protein building by the gene to be inhibited
B A POLYPEPTIDE CHAIN TO BE PRODUCED WITH MAJOR CHANGES IN ITS AMINO ACID SEQUENCE
C  a polypeptide chain to be produced with only one amino acid changed in its sequence
D transcription of mRNA and translation by RNA to be inhibited



I think to is B
