Explanation:
Related genes in bacteria are often found in a cluster on the chromosome, where they are transcribed from one RNA polymerase binding site(promoter) as a single unit while other regulatory proteins are binding repressors attached to DNA pieces known as operators. When they are bound to operator, a repressor reduces transcription.
Genes in cases like this encode proteins, having various roles which include fuel metabolism, maintenance of cell structure, and
also defense against viruses in its process. A great number of these proteins are been used while others are needed only under certain decrees. Therefore, it is said that cells don't express all the genes in their genome always.
