Ideally a DNA molecule should
in a perfect way. Sometimes however
failures in the duplication occur, with
alteration (deletion, addition or
substitution) of one or more
in the molecule.

Those mistakes,or , therefore
make changes in the protein synthesis
process too. For example, the
production of an important for
cells or may be suppressed, new
utile or inutile proteins can be created,
etc. The mistake in the DNA
and the resulting production of altered
genetic material are some of the main
creative forces for the
evolution and the diversity of .
