Steroid hormones usually act via receptors that are coupled

Steroid hormones usually act via receptors that are coupled to G proteins that activate adenylyl cyclase activate phospholipase C. bind to DNA. activate tyrosine kinases.

Solution

Steroid hormones are a special class of hormones which are secreted by the adrenal glands and the reproductive organs. They are derivatives of cholesterol and can be classified according to the receptors they bind in order to carry out cellular functions.

The mode of action followed by most steroid hormones are that, they regulate the transcription of genes within the nucleus of cells. Hence, unlike other hormones or cellular messenger molecules which bind to receptors on the cell surface, the steroid hormones bind to receptors located on the nucleus. The steroid-receptor protein complex binds to the DNA and carries out its activity.

Thus, the correct option is C) bind to DNA.
