Considering the following events in the nuclear receptor model, identify which of these events occurs in the nucleus.
(1) Hormone receptor complex binds to DNA.
(2) Messenger RNA directs synthesis of specific proteins.
(3) Hormone binds to receptors in the nucleus (sometimes in the cytoplasm) .
(4) Messenger RNA synthesis is activated.
(5) Synthesized proteins produce the response of the cell.
A) 1, 3, 5
B) 1, 3, 4
C) 1, 2, 3
D) 3, 4, 5
E) All events occur in the nucleus.
Nuclear Receptor Model
Describes the mechanism by which certain types of receptors within cells bind to specific molecules, like hormones, and regulate gene expression.
Messenger RNA
A type of RNA that conveys genetic information from DNA to the ribosome, where it specifies the amino acid sequence of the protein products.
Synthesized Proteins
Proteins created through the process of translation where ribosomes construct protein molecules from RNA messages.

Final Answer :
B
Explanation :
Events 1, 3, and 4 occur in the nucleus. Hormone-receptor complexes bind to DNA in the nucleus, hormones can bind to receptors that are located in the nucleus, and the activation of messenger RNA synthesis also occurs in the nucleus.
