Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

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 ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
