what are the types of mutations?
The types of mutations include: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. A nonsense mutation is also a change in one DNA base pair.
Missense mutation (illustration) This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. A nonsense mutation is also a change in one DNA base pair.
1 Insertion â when a base is added to the sequence. 2  Deletion â when a base is deleted from the sequence.  Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. These regions of DNA can be between 10,000 and 5,000,000 bases long.
