A change of nucleotide sequence in a genome of a virus, organisms, extrachromosomal DNA, or other genetic elements that occur permanently is called mutation. Environmental factors also cause mutation such as ultraviolet radiation from the sun or it can be caused by errors that occur during replication of DNA.
