REY [17]

Action potential refers to the electrical signal. Propagation of action potential along the membranes of these cells results in muscle contraction and functioning of neurons.

Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.
