It is worthwhile re membering that the first examples of unstable genomes were described for maize before DNA was known to be the genetic material. Exchanges of genetic material have been demonstrated within organelle DNA, between organelle DNAs or between organelle and nuclear DNAs.

Mutations (recognised by a change in phenotype) label genes and can be used to study gene structure, gene function and the organisation of the genome. It is self evident that only by studying phenotype ("Biochemistry") can we do "Ge netics" and that "Genetics" (perturbation of the phenotype) is the key to understanding the "Biochemistry".
