Consider the following events in the nuclear receptor model: (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)

Events 1, 3, and 4 occur in the nucleus. The hormone receptor complex needs to bind to DNA in the nucleus to start the process. Hormone binding to receptors can occur in the nucleus or cytoplasm, but it is generally more common for nuclear receptors to be located in the nucleus. Messenger RNA synthesis occurs in the nucleus, which is where transcription occurs. The synthesized proteins then carry out their function within the cell, which could be in either the nucleus or cytoplasm.
