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 ...
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 ...

A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
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 ...
