WebFrameshift mutations in microsatellites can be identified by extraction of DNA from both normal and tumor tissue (usually paraffin-embedded tissue), amplification of selected … WebInsertions can be particularly hazardous if they occur in an exon, the amino acid coding region of a gene. A frameshift mutation, an alteration in the normal reading frame of a gene, results if the number of inserted nucleotides is not divisible by three, i.e., the number of nucleotides per codon. Frameshift mutations will alter all the amino ...
