The homeobox sequence codes for a 60 amino acid protein domain known as the homeodomain. The main role of homeodomain is to act as a switch that controls gene transcription. See also: Hox gene.

The opposition to current flow in an electrical circuit is called _____. resistance The law that defines the relationship between current, voltage and resistance is called _____ Law.
Collector-emitter: The main current that flows through the transistor. Voltage placed across the collector and emitter is often referred to as V ce, and current flowing through the collector-emitter path is called I ce. Base-emitter: The current path that controls the flow of current through the collector-emitter path.n a PNP transistor, the emitter is the positive side of the transistor. The collector and base are the negative sides. Most circuits that you can build with an NPN transistor can also be built with a PNP transistor. But if you do, you must remember to flip the power connections.
