Solution

The correct option is A True
Prokaryotes being simpler organisms than eukaryotes, need an organised system for the functioning of their genome. Thus, they have polycistronic genes in which a cluster of genes can be expressed simultaneously, while eukaryotes mostly have monocistronic genes, each being expressed individually.
