WebOct 23, 2024 · Further, the fine genetic structure of the T4 rII region indicated that there were two distinct “cistrons” (Fig. 9C). Cistrons were defined as groups of mutants, any one of which could complement mutants of another group, but could not necessarily complement mutants within their own “cistron” group. The words cistron and gene were coined before the advancing state of biology made it clear that the concepts they refer to are practically equivalent. The same historical naming practices are responsible for many of the synonyms in the life sciences. The term cistron was coined by Seymour Benzer in an article entitled … See more A cistron is an alternative term for "gene". The word cistron is used to emphasize that genes exhibit a specific behavior in a cis-trans test; distinct positions (or loci) within a genome are cistronic.
