WebJan 13, 2024 · A missense mutation occurs when there is a mistake in the DNA code and one of the DNA base pairs is changed, for example, A is swapped for C. This single change means that the DNA now encodes for a different amino acid, known as a substitution. Sometimes a change in the amino acid has no effect on the resulting protein's function at … WebDuplication: A duplication consists of a piece of DNA that is abnormally copied one or more times.
