Chapter 7.4, Problem 1MQ
Summary Introduction
The regulation of transcription is controlled by the repressor or inducer protein. The positive regulation is controlled by the inducer proteins that stimulates the synthesis of mRNA molecules. The negative regulation is controlled by repressor proteins that blocks the mRNA synthesis.
