They can also appear spontaneously during the replication of DNA. Mutations generally fall into two types: point mutations and chromosomal aberrations. In point mutations, one base pair is changed.

There are many different types of mutations which can arise in DNA. This diagram shows the normal order of the bases for one of the strands in a DNA molecule. Only one of the strands of DNA is ...

However, most DNA mutations do not alter a protein, they only alter it slightly so its appearance or function is not changed. There are many different types of mutations which can arise in DNA.
