Gene Regulation

Question 1

What is the Operon

Answer 1

a cluster of linked genes that all share a common promoter and are transcribed at the same time.

Question 2

Promoter

Answer 2

Binding site of RNA polymerase

Question 3

what is a Structural genes and where are they found.

Answer 3

Structural genes are responsible for producing proteins that are involved in the structure or
function of a cell. For example, they may code for enzymes, transport proteins, receptors,
or peptide hormones. These genes are often found downstream (towards the 3’ end of the
coding strand) of the regulatory gene that controls them.

Question 4

What is a regulatory gene?

Answer 4

Regulatory genes are responsible for the production of regulatory proteins such as repressor proteins, which inhibit or decrease the expression of structural genes.

Question 5

what is an Activator Proteins

Answer 5

A protein coded for by a regulatory gene that increases gene expression.
