[Answer] In humans the hormone testosterone enters cells and binds to specific proteins which in turn bind to specific sites on the cells’ DNA. These proteins probably act to do what?

Answer: help RNA polymerase transcribe certain genes Testosterone stimulates the expression of genes involved in male sexual characteristics; it follows that the proteins that it interacts with and which bind to DNA will promote transcription.

Sat Nov 10 2001 13:30:00 GMT-0500 (Eastern Standard Time) · Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events most commonly protein phosphorylation catalyzed by protein kinases which ultimately results in a cellular response. Proteins responsible for detecting stimuli are generally termed receptors although …

They can do so because they are lipid-soluble. The combined hormone -receptor complex then moves across the nuclear membrane into the nucleus of the cell where it binds to specific DNA sequences regulating the expression of certain genes and thereby increasing the levels of the proteins encoded by these genes.
