Although telomeres are fragile, they don't have to be handled with care. Researchers now show that what keeps our fragile telomeres from falling apart is a protein known as TRF1 that ensures the smooth progression of DNA replication to the end of a chromosome. The work not only shows how telomeres help chromosomes protect their vulnerable ends but also reveals how the genome is made more stable by them.
