Telomeres aid in the replication of the ends of chromosomes by providing a buffer zone of non-coding DNA sequences that are repeated thousands of times. This prevents the loss of important DNA sequences from the ends of chromosomes during replication, as each round of DNA replication results in the shortening of chromosomes.
