WebTransversion substitution refers to a purine being replaced by a pyrimidine, or vice versa; for example, cytosine, a pyrimidine, is replaced by adenine, a purine. Mutations can also be the result of the addition of a nucleotide, known as an insertion, or the removal of a base, also known as deletion.
