Answer: 2. Binding to DNA and forming a gene-hormone complex.

Steroid hormones are lipid-soluble, so they enter the cell and bind to intracellular receptors. The hormone-receptor complex binds DNA and regulates gene expression (transcription).

Cyclic AMP and membrane receptors are used by peptide hormones. Option 2 is correct, as it describes the hormone-gene complex acting on DNA.
