Cistron - an overview ScienceDirect Topics

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. WebBut Benzer demonstrated in 1955 that gene consists of several units of cistron, recon and muton which are the units of function, recombination and mutation within the gene. 4.
