WebFeb 4, 2024 · A point mutation—the change of a single nitrogen base in a DNA sequence —is usually the least harmful type of DNA mutation. Codons are a sequence of three nitrogen bases in a row that are "read" by messenger RNA during transcription. That messenger RNA codon is then translated into an amino acid that goes on to make a protein that will be ... WebIn some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells.
