Steroid hormones pass through the cell membrane and bind to a specific steroid hormone receptor protein. The combined steroid and receptor protein then bind to a specifiâ¦c sequence of bases in the DNA molecule. This sequence of bases is part of the promotor of a gene.   Binding of the steroid - receptor complex either activates (switches on) or represses (switches off) the gene which is controlled by that promotor.
