Homework Answers
Operon is a functional unit of DNA which contains cluster of genes.
Advantage:-
- Helps in coordination of protein synthesis
- It helps in the synthesis of group of functionally related enzymes.
Regulons are group of genes regulated as a single unit
Advantage:-
- Helps in the synthesis of proteins involved in generating energy effectively.

Question 12 2 pts What is the role of CAMP in regulation of the lactose operon?...
Question 12 2 pts What is the role of CAMP in regulation of the lactose operon? CAMP is a repressor of the lactose operon and turns off gene expression of the lactose operon CAMP is an activator and prevents the repressor protein from binding to the operator region of the operon which allows for the lactose operon to be turned "on". 5 CAMP is an inducer of the lactose operon and also an activator since it prevents the repressor protein...
