The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

The shape and morphology of a cell play a key role in the biological function. This corresponds to the principle of "form follows function," which is common in modern fields of design and architecture ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

The cancer drugs called PARP inhibitors have a puzzling reputation: even though they are treatment mainstays for multiple forms of cancer, they can damage cancer-killing T cells and disrupt the ...

FARGO, N.D.--(BUSINESS WIRE)--Aldevron, a global leader in the production of DNA, RNA and protein, has launched its latest innovation, Alchemy™ cell-free DNA technology. This revolutionary technology ...

Scientists have built a synthetic cell from scratch in a world-first breakthrough that paves the way for creating entirely ...
