In all living organisms, proliferating cells go through the fundamental process of DNA replication. Through this process, they faithfully duplicate their DNA and divide into two daughter cells. In ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this happens, your entire genetic library — your genome, which totals more than ...

Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

DNA replication is happening continuously throughout the body, as many as trillions of times per day. Whenever a cell divides—whether to repair damaged tissue, replace old cells, or simply to help the ...

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma ...

Reactive oxygen species (ROS) were long regarded as harmful by-products of mitochondrial metabolism, but growing evidence—including our own—shows that ROS also signal to core processes such as ...

DNA is the molecule that holds the instructions for all living things. DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Check your ...
