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