Explanation:
Detailed explanation-1: -The process of turning genes on and off is known as gene regulation. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example.
Detailed explanation-2: -So, Regulatory genes are involved in turning off or on, the transcription of a set of genes. Operator gene-It controls the synthesis of mRNA over the structural genes.
Detailed explanation-3: -When a gene is turned off, it no longer provides the directions for making proteins. This means that the proteins needed to fulfill a particular job–say, tolerate lactase–aren’t produced.
