Question

Quizplus · Accepted Answer

Telomeres are sequences of non-coding nucleotides at the ends of chromosomes. They play a crucial role in protecting the genetic material of the chromosome during cell division and preventing the loss of important genetic information. As cells divide, the telomeres gradually shorten until they reach a critical length which triggers cellular senescence or cell death.
