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 ...

New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...

You may think that a virus is a virus, and they all afflict living things more or less the same. Yet while it is true that viruses attack most everything on Earth, the viruses that do the vexing ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...
