Direct gene activation involves a second-messenger system.

Question

Quizplus · Accepted Answer

Direct gene activation does not involve a second-messenger system. It involves the binding of a transcription factor directly to DNA to activate gene expression. Indirect gene activation, on the other hand, involves a second-messenger system, such as a hormone binding to a membrane receptor to activate a cascade of intracellular signaling molecules that ultimately lead to gene expression.
