________ hormones bind with an intracellular receptor to form a ________, which activates specific genes.
A)Steroid and thyroid; receptor-hormone complex
B)Steroid and thyroid; DNA-mRNA complex
C)Nonsteroid; receptor-hormone complex
D)Nonsteroid; DNA-mRNA complex

Question

Quizplus · Accepted Answer

Steroid and thyroid hormones can pass through the cell membrane and bind with intracellular receptors to form a receptor-hormone complex, which can then activate specific genes. Nonsteroid hormones, on the other hand, bind with cell surface receptors and initiate a second messenger system within the cell, which ultimately leads to activation of specific genes. Therefore, option A is the best choice as it correctly identifies the hormones that bind with intracellular receptors and the resulting complex that activates specific genes.
