Telomeres cap chromosome ends and shorten as cells divide
Repetitive nucleotide sequences protect genetic data during cell replication cycles
Telomeres are repetitive non-coding DNA sequences located at the ends of linear chromosomes that protect genomic integrity during replication. Because standard DNA polymerase enzymes cannot replicate the very tip of a chromosome, telomeres shorten slightly with each cell division cycle. When telomeres become critically short, cells enter senescence or undergo cell death.

Telomeres cap chromosome ends and shorten as cells divide: the short answers
- Where does this come from, and can I check it?
- Repetitive nucleotide sequences protect genetic data during cell replication cycles. The figure is taken from Nobel Prize, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a science fact?
- Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
