Question

Direct gene activation involves a second-messenger system. True or False

Answer 1

Answer: The statement is true

Explanation:

Gene activation is one of the ways hormones exert their functions. And this require a second messenger system.

Usually, the hormone:

- binds to a specific receptor protein on the target cell

- the bound-complex causes the formation of second messengers such as cAMP (a cyclic nucleotide) that diffuses into the nucleus and binds directly with DNA, ACTIVATING GENE and switching "on" or "off" protein synthesis.

Answer 2

The answer to this question is true.
