DNA Mutation

 

Genes can be mutated in several different ways. The simplest type of mutation involves a change in a single base along the base sequence of a particular gene--much like a typographical error in a word that has been misspelled. In other cases, one or more bases may be added or deleted. And sometimes, large segments of a DNA molecule are accidentally repeated, deleted, or moved.
