Frameshift mutations are insertions or deletions in the genome that are not in multiples of three nucleotides. They are a subset of insertion-deletion (indel) mutations that are specifically found in the coding sequence of polypeptides. Here the number of nucleotides that are added or removed from the … See more Frameshift mutations are among the most deleterious changes to the coding sequence of a protein. They are extremely likely to lead to large-scale changes to polypeptide length and chemical composition, … See more The core reason for the presence of frameshift mutations is the body’s mechanism for translating genetic information into amino acid sequences through a triplet … See more The image above shows the nucleotide and amino acid sequences in a wild type protein as well as the result of a nucleotide insertion, leading to the incorporation of incorrect amino acids and the premature end to polypeptide … See more WebDec 15, 1989 · The frameshift mutation, which is present on both alleles, causes premature termination four codons downstream, and the loss of a very hydrophilic stretch of 22 amino acids.
