Final answer:
Steroid receptors are found in both the cytoplasm and nucleus of cells and can bind to specific DNA sequences to regulate gene expression. The false statement is that steroid receptors are only found in certain tissues.
Hence the correct answer is option 4
Step-by-step explanation:
The FALSE statement about steroid receptors is that they are only found in certain tissues. Steroid receptors are actually found in both the cytoplasm and nucleus of cells. When a steroid hormone enters a target cell, it binds to a receptor protein to form a hormone-receptor complex. This complex can then move to the nucleus and bind to specific DNA sequences, ultimately regulating gene expression. Therefore, statement 4 is incorrect.
