Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation. Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair.
The types of mutations include: Missense mutation 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.Nonsense mutation A nonsense mutation is also a change in one DNA base pair.eport Abuse. The DNA sequence of a gene can be altered in a number of ways. Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins.
