- Definition mutation in DNA or RNA molecule involving a change (replacement or substitution) of only one nucleotide base Reference "COM-EN, based on: Biology Online http://www.biology-online.org/dictionary/Base_pair_substitution & http://www.biology-online.org/dictionary/Point_mutation [20.9.2010]"
- Comment "This type of mutation occurring in noncoding sequences often does not result in an altered amino acid sequence during translation. If a mutation in the promoter sequence of a gene occurs, the effect may be apparent since the expression of the gene may cause changes in the amino acid sequence, as well as the structure and function of the protein product.Point mutations may be classified on the basis of functionality:- nonsense mutation- missense mutation- silent mutation Depending on the type of nitrogenous base involved, this type of mutation may be categorized as:- transition- transversion Not to be confused with the broader term gene mutation [ IATE:1351106 ] which also covers frame shift mutation [ IATE:1687482 ]."
