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

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 ...

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

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 ...

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 ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

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 ...
