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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A simulated cell in the early stages of division. Left half shows cytoplasm (blue cubes), mRNA degradation machinery molecules ...

A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

Discovery reshapes understanding of how tumor cells repair broken DNA, pointing toward more precise cancer therapies.

Scientists at the University of Leicester have captured the first detailed "molecular movie" showing DNA being unzipped at the atomic level – revealing how cells begin the crucial process of copying ...

Like jewels in a vault, our precious genetic material is stored in the nucleus of a cell--sequestered away from potentially damaging cellular components and toxins so that no harm can come to it. Yet ...

Drs Ursula A. Matulonis and Joyce F. Liu discuss targeting DNA damage and repair and replication stress in endometrial cancer. Drs Ursula A. Matulonis and Panagiotis A. Konstantinopoulos discuss ...

In the DNA fiber assay used in this study, cells labeled with IdU (green) and CldU (red) nucleotide analogs were sorted into substages of S phase before being subjected to the DNA fiber assay. This ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life reconstructions ever created. Using computer technology, scientists have ...
