Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

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 ...

Scientists have developed a method for producing biological crystals that has allowed scientists to observe -- for the first time -- DNA double chain breaks. They have also developed a computer ...

A quiet but critical DNA process that begins even before birth may hold the key to understanding infertility, recurrent miscarriages, and genetic conditions like Down syndrome. Researchers at UC Davis ...

Day in and day out, in our bodies, the DNA in cells is damaged for a variety of reasons, and thus intercellular DNA-repair systems are fundamental to the maintenance of life. Now scientists from the ...

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 ...
