Question

Which of the following changes to a DNA sequence would cause a frameshift mutation? A. The second codon of a protein coding sequence changes from alanine (GCT) to alanine (GCC). B. The thirtieth codon of a protein coding region changes from serine (TCG) to proline (CCG). C. At a position immediately following the fifteenth codon of a protein coding region, five base pairs were inserted (GGTTG). D. The tenth codon of a protein coding region, which normally codes for glycine (GGT) is absent. E. The seventy-fifth codon of a protein coding sequence changes from a tryptophan codon (TGG) to a stop codon (TGA).
