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.
I have a new Dell D630 notebook computer and I wanted to run dual 24inch monitors while I am in the office. I have the Dell advanced port replicator (docking station) that gives me two video outputs. One is an analog VGA and the other is DVI. The video card in the laptop is the Quadro NVS 135M.
