b. How do inducible operons (e.g., the lactose operon) and repressible operons (e.g., the tryptophan operon) benefit a bacterial cell?

(5 marks) 5. Explain the possible role of telomerase in cellular aging and in cancer formation.

(6 marks) 6. a. Draw a diagram to show what could happen during meiosis that would result in an egg with two X chromosomes.
