Question

Quizplus · Accepted Answer

Telomeres are specialized DNA sequences that are located at the ends of chromosomes. They consist of repeated nucleotide sequences that protect the genetic information of the chromosome from being lost during DNA replication. As cells divide, telomeres gradually shorten, leading to cellular senescence and/or apoptosis due to chromosome instability.
