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.
That is called Ohm's Law. Ohm's Law describes the behavior of a theoretical circuit element called a resistor which usually has a constant value of resistance. Actual resistors (and actual conductors) behave very much like the theoretical model. Changing the current through a resistor does not have any effect on the resistance. If the current goes up, then according to Ohm's law, the voltage must have gone up in the same proportion. There is a circuit element called a variable resistor (a.k.a., potentiometer, or rheostat).
