Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a ...

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 ...

Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...

The artificial cell nucleus (right) constructed using the purified DNA was morphologically very similar to the natural cell nucleus derived from an egg (left). A team led by Professor Kazuo Yamagata ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

Paras Gaur, a postdoctoral researcher at the University of Iowa, investigates DNA damage repair and G-quadruplex structures ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) ...

In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins - essential building blocks of ...

Macrophages, the immune system’s front-line scavenger cells, do more than simply digest dead cells. A new study published in ...
