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 ...

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 ...

Discovering How DNA Reaches Its Most Compact Form For many years, researchers did not know how this extra level of chromatin compaction occurred. In 2019, HHMI Investigator Michael Rosen and his team ...

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 ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...

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

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 ...
