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 ...

Telomere is a repeated sequence (TTAGGG)N that caps the end of the chromosomes to protect them from damage during DNA replication prior to cell division. Telomere length is essential to the cell's ...

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 ...

Similar to the way the caps on the ends of a shoelace prevent it from fraying, telomeres—regions of repetitive DNA sequences and a protein structure—protect the tips of chromosomes from damage.

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 ...
