This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

BUFFALO, N.Y. -- Piero Bianco produces movies. Not films that chronicle the human condition, a la Hollywood. His subject is human biology at its most basic -- the translocation and unwinding of DNA by ...

THUWAL, Saudi Arabia — Scientists have finally captured footage of the microscopic machinery that allows our cells to copy ...

This schematic depicts molecules of the DNA repair protein, Rad51 (green ovals), assembling into a filament on an optically trapped DNA molecule. Below, a series of images shows a fluorescently ...

A new technique for creating artificial DNA that is faster, more accurate and more flexible than existing methods has been developed by scientists. A new technique for creating artificial DNA that is ...

As we and other vertebrates age, our DNA accumulates mutations and becomes rearranged, which may result in a variety of age-related illnesses, including cancers. Biologists Vera Gorbunova and Andrei ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

A study of where and how an enzyme cuts DNA may have inadvertently revealed a basic principle of gene regulation, say researchers in Boston Children's Hospital's Program in Cellular and Molecular ...

In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...
