Q. _______ proposed the operon model of gene regulation in prokaryotes.
Solution:
The operon model of prokaryotic gene regulation was proposed by Jacob and Monod. Operons are groups of genes, coding for related proteins, and are arranged in units.
It is the part of the DNA which act as a single regulated unit having one or more structural gene, an operator, a promoter, and a regulator gene.
i-gene is the regulatory gene that produces repressor protein. It inhibits the expression of the structural gene. Such regulation of gene is called negative regulation. The structural gene includes Z, Y and A gene that produces beta-galactosidase, permease and transacetylase enzyme respectively.
