DNA Sequencing, Mutation and Repair A nonsense mutation introduced into the DNA sequence of a gene may cause a shift in reading frame cause premature termination of the mRNA have no effect on the transcript or protein made shorten the length of the protein encoded by the gene cause a shift in reading frame cause premature termination of the mRNA have no effect on the transcript or protein made shorten the length of the protein encoded by the gene ANSWER DOWNLOAD EXAMIANS APP
