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.
USB Hub vs Port Replicator. Posted by Scottish Storm on 14 May 2004 2:01. Apologies if this thread has already been discussed to death, but I was fishing for opinions. I'm considering either a USB Hub (Belkin's 7-port hub, for instance) or a (likely Targus) port relicator for my i5150.
