CHAPEL HILL – A new study from scientists at the UNC School of Medicine has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

University of Pittsburgh researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

Could yeast and humans be any more different? Going by looks alone, probably not. But peering into our genomes reveals ...

Adult cells in our body can only give rise to the same cell type. For example, a skin cell cannot give rise to a muscle cell but to skin cells only. This limits the potential use of adult cells for ...

Researchers have found that the “mother” of all stem cells, known as totipotent stem cells, have a much slower rate of DNA replication, which helps improve their efficiency at differentiating into ...
