A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...

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 ...

These sequences are extremely prone to mutations and rank among the most functionally important regions in the entire human ...

Our DNA is compacted and arranged into chromosomes, most of which are shaped like X’s. The ends of the chromosomes arms are ...

A new discovery offers hope for Huntington’s disease. This discovery provides hope that a DNA repair process may help slow or stop disease progression. Research has identified a critical DNA repair ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

In the early 1980s, David Gilmour, now an emeritus biochemistry and molecular biology professor at Pennsylvania State University, joined the laboratory of geneticist and biochemist John Lis as a ...

As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.
