Answer
Telomerase, an enzyme co-discovered by Elizabeth Blackburn, plays a crucial role in maintaining the integrity of chromosomes. It adds repetitive DNA sequences to the ends of chromosomes, called telomeres, which shorten with each cell division. Telomerase counteracts this shortening, allowing cells to divide more times and potentially preventing age-related diseases and cancer.
