What is the primary function of telomerase enzyme?

Correct option is B

The correct answer is (b) Telomere lengthening.
• Telomerase adds repetitive sequences to chromosome ends (telomeres).
• It prevents loss of genetic material during cell division.
• Active mainly in germ cells, stem cells, and cancer cells.
Information Booster:
• Telomeres shorten with age in most somatic cells.
• Telomerase activity is linked to cell longevity.
• Discovered by Elizabeth Blackburn and Carol Greider.
Additional Knowledge:
• Excess telomerase activity is associated with cancer.
• Normal somatic cells have very low telomerase activity.
