The phenomenon of lysogeny was cited by Jacob and Monod in 1961 as an example of gene control by repressors. It was hypothesized that each temperate phage produces a repressor which specifically blocks the functioning of early genes of that phage. Since the late genes function only if provided with certain early gene products, the proposed repressor action would suffice to turn off all the lytic phage genes, thereby permitting lysogenization. According to these ideas, the dormant phage genes would resume functioning upon removal of the repressor, and it was proposed that inducing agents, such as UV light, function by inactivating the repressor.
Chadwick et al. (Thu,) studied this question.
