Question

Difference between a structural gene and a regulatory gene.

Answer 1

A structural gene is a gene that codes for any RNA or protein product other than a regulatory element (i.e. regulatory protein).

regulator gene is a gene that controls the expression of a structural gene by directing the synthesis of a gene regulator that binds to a gene operator and affects the synthesis of the structural gene's protein product

A regulatory gene is a nosy gene whose prime preoccupation is to horn in on other genes and control the rate at which they make products
