The structural genes in an operon lie adjacent to one another.

The structural genes in an operon lie adjacent to one another. Correct Answer True

The structural genes code for the enzymes involved in metabolic pathways. The genes are located adjacent to each other and the RNA polymerase moves through the structural genes one after the other, transcribing all of the genes into a single mRNA.
