Binary switch gene

Answer 1)

Two operational representations, binary and graded, have been planned for the mechanism of eukaryotic gene induction. The binary model compete that at a given instant, a promoter, i.e., the regulatory district of a gene, can only assume one of two discrete transcriptional states: active and inactive.

Answer 2)

Lin-12 was identified in a genetic screen for mutations that have defective vulval development. The first alleles exposed, called lin-12(d) alleles, were leading and hypermorphic, and intragenic deterioration yielded null alleles, called lin-12(0). Phenotypic analysis indicated that lin-12(d) and lin-12(0) alleles cause opposite transformations in many ...
