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.
A USB adapter is a small and compact external, physical component that takes a device lacking USB function and converts it for operation with other USB technology like a port or device. These adapters are absolutely necessary for plug-and-play capabilities for a non-supported device. Card readers, webcams and Internet or LAN connections are examples that commonly call for the use of a USB adapter. If a computer is designed with a USB port, then an adapter is most certainly supported. A USB adapter is versatile in the way that it can offer a user the option to connect multiple devices for simultaneous operation.
