"WebGene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made. There are two key steps involved in making a protein, transcription and translation. " - Gene expression higher biology
