A substitution mutation replaces one base with another, resulting in a change in only one chemical letter. This transition might be caused by a variety of factors relating to the storage and reading of DNA. Nucleotides tend to come off during the depurination process.
WebA conservative replacement (also called a conservative mutation or a conservative substitution) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size)..
