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.
A port replicator is an attachment for a notebook computer that allows a number of devices such as a printer, large monitor, and keyboard to be simultaneously connected.
The computer is an HP Touch Smart 610-1065qd. I connect to the second monitor by way of an HP 2005pr USB 2.0 Port Replicator. The Replicator appears as a drive when looking at This PC and referees to it as HP USB DOCK, as it did in Windows 7.
