Telomeres are specialized structures at the ends of chromosomes that prevent fusion events and promote chromosomal end replication. Telomeres are maintained by the regulation of telomerase activity ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

A new study led by researchers at the University of Pittsburgh (Pitt) and UPMC Hillman Cancer Center has shown that an enzyme called PARP1 is involved in the repair of telomeres, the lengths of DNA ...
