Answer 1

Answer:

Regulon

Explanation:

A regulon comprises of a group of operons that are controlled by the same regulatory protein referred to as a regulator which could act as a repressor or activator.

Regulons in bacterial cells are referred to as the fundamental unit of the response system. Regulons are majorly used when referring to prokaryotes that have their genome organized to operons, although this term is not limited to that. The genes that are found in a regulon are arranged into two or more operons at different regions on the chromosome.
