MADISON — Researchers at the University of Wisconsin–Madison have described the way an enzyme and proteins interact to maintain the protective caps, called telomeres, at the end of chromosomes, a new ...
Our DNA is compacted and arranged into chromosomes, most of which are shaped like X’s. The ends of the chromosomes arms are ...
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 ...
CST (purple/lavender) bound to POT1 (red). Phosphorylation of the crimson-highlighted region in POT1 regulates the recruitment and activity of CST–Polα-primase at telomeres. The length of telomeres ...
Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten ...
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 Shortening and Aging Telomeres affect how our cells age. Once they lose a certain number of bases and become too short, the cell can no longer divide and be replicated. This inactivity or ...
The stress that some mothers experience during their pregnancies could influence the genetic makeup their babies are born with and, eventually, lead to premature biological ageing and associated ...
