Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

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 ...

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 ...

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 ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

A team of Penn State scientists has shed light on the processes that lead to certain human DNA mutations that are implicated in hundreds of inherited diseases such as tuberous sclerosis and ...

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 ...

The complex appears to reel in the DNA around the mismatch as well, marking and protecting the DNA region until repair can occur. "Due to the mobility of these proteins, current thinking envisioned ...
