Scientists have shown that in one in every 4,000 births, some of the genetic code from our mitochondria – the ‘batteries’ that power our cells – inserts itself into our DNA, revealing a surprising new ...
The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...
A study published in Nature Medicine found that monkeypox viruses from the current outbreak have on average 50 differences in their DNA compared to the versions from about four years earlier. That’s ...
