The length of telomeres that protect the ends of our chromosomes should be tightly regulated. Those that are too long predispose to cancer, and those that are too short lose their protective ability, ...

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

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 ...

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 ...

Studies have reported that telomeres consisting of repeated DNA sequences (TTAGGG) play an essential role in protecting the human chromosome ends from fusions and degradation. Replication of cells ...

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 ...

In a study of 17 people from five families, Johns Hopkins Medicine researchers say they found that ultra-lengthy DNA endcaps called telomeres fail to provide the longevity presumed for such people.

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 ...

New findings describe how the enzyme CST is recruited to the end of the telomere, where it maintains telomere length with the help of subtle chemical changes made to the protein POT1. The length of ...

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 ...
