Term
coined by Benzer for the smallest genetic unit that does NOT show
genetic complementation when two different mutations are in trans
during a cis-trans complementation test; but shows wild-type phenotype
when the same mutations are in cis. Synonymous with gene. Originally
defined as a functional genetic unit within which two mutations cannot
complement. Now equated with the term gene, as the region of DNA that
en codes a single polypeptide (or functional RNA molecule such as
tRNA or rRNA). |
