Question

Quizplus · Accepted Answer

Telomeres are DNA segments located at each end of a chromosome. They act as protective caps to prevent the loss of genetic information during cell division. As cells divide, the telomeres gradually disintegrate, eventually leading to cell senescence and aging. Telomerase, an enzyme that adds DNA sequence repeats to telomeres, can lengthen the lifespan of cells by delaying the erosion of telomeres.
