Question

For steroid hormones, receptors are located on/in:

• A. Plasma membrane
• B. Cytoplasm
• C. Nuclear membrane
• D. DNA

Answer 1

The correct option is D DNA

Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors. Receptors present inside the target cell are called intracellular receptors, mostly nuclear receptors (present in the nucleus). Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex. Hormones which interact with intracellular receptors (e.g., steroid hormones, iodothyronines, etc.) mostly regulate gene expression or chromosome function by the interaction of hormone-receptor complex with the genome (DNA). Cumulative biochemical actions result in physiological and developmental effects
