Mutations

• Point mutations (substitutions, insertions, deletions) can change the sequence of amino acids in a protein, potentially altering its function.

  • Silent mutation: No effect on the protein.

  • Missense mutation: A single amino acid is changed.

  • Nonsense mutation: The change creates a stop codon, shortening the protein.

  • Frameshift mutation: Insertion or deletion of nucleotides shifts the reading frame, potentially altering every subsequent amino acid.
