The terminal sequences of DNA that protect the ends of chromosomes from deteriorating are called telomeres.

Telomeres are repetitive nucleotide sequences located at the ends of chromosomes. They play a crucial role in cellular aging and stability, preventing the loss of important genomic information during DNA replication. Over time, as cells divide, telomeres shorten, which is associated with aging and the eventual limit on the number of times a cell can divide, known as the Hayflick limit. The enzyme telomerase helps maintain telomere length in certain cell types, such as stem cells and cancer cells, contributing to their ability to divide indefinitely.
