Mutations are changes in the nucleotide sequences in a genome. Most often, these minor mistaks are corrected by in-built repair mechanisms and many mutations go unnoticed an are not harmful. Harmful mutations cause diseases in many cases. There are several factors that promote the formation of mutations. These factors are called mutagenic agents. Mutagenic agents are divided into: chemical and physical mutagens. UV radiation is an example of a physical mutagen and Nitrous acid is an expample of a chemical mutagen
