Life may have emerged from a surprisingly simple network of chemical reactions long before cells or genes existed.

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

Specialised DNA testing is being used to identify seven children among the 43 victims of a tragic Limpopo bus accident. Preliminary investigations revealed the bus was overloaded, unroadworthy, and ...

This is a preview. Log in through your library . Abstract In eucaryotic cells chromosomes must be fully replicated and repaired before mitosis begins. Genetic studies indicate that this dependence of ...

Modern genetic studies show that up to 4% of human DNA comes from Neanderthals—and some of those ancient genes affect how our bodies break down medications today. Researchers have identified variants ...

Origin firing is the initiation of DNA replication that takes place at specialised start sites, or replication origins, where the DNA first has to be opened up and unwound, before DNA synthesis ...

Despite the success of protease and reverse transcriptase inhibitors, new drugs to suppress HIV-1 replication are still needed. Several other early events in the viral life cycle (stages before the ...
