Question
Chapter 12.2, Problem 2CC
Summary Introduction
To analyze:
The meaning of the terms negative control and inducible with regard to regulatory proteins and small effector molecules.
Introduction:
The term negative control means the decrease of the rate of transcription due to the action of repressors. Because the repressor can bind with DNA to decrease the production of proteins. Lac operon is said to be inducible because it can either express its genes or repressed by regulatory proteins.
