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 ...

Imagine your DNA as a set of shoelaces. Telomeres are like the plastic tips at the ends of those shoelaces, preventing them from fraying and unraveling. Structurally, telomeres are repetitive ...

In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...

Every human cell packs roughly two meters of DNA into a nucleus only six micrometers wide. That ratio, confirmed by ...

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of ...

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 ...

Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...

As DNA strands ravel and unravel in an intricate dance, one notable event takes center stage: replication. This process is essential to life, but the finer details of its orchestrated steps are still ...
