Multiple Choice

True or False: if false, choose the answer that best corrects the statement.

Steroid hormones are the only hormones that interact with the DNA via a receptor-hormone complex.

True.

False; all hormones can interact with DNA via a receptor-hormone complex; it depends on what type of receptor is used at the target cell.

False; thyroid hormone is an amino-acid based hormone that interacts with DNA via a receptor hormone complex.

False; most peptide hormones interact with the DNA via a receptor complex, while most steroid hormones use second messenger systems.
