Mutation Is Random
... A mutation is a change in the sequence of DNA in the genome of an organism. It can be a single base change—for example a G changing to an A—or mutation can involve a longer stretch of DNA, including the gain and loss of genes and other largescale changes. A glossary of different types of changes is ...
