A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's ...
Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...
When the molecular machinery in our cells gets to work transcribing the genetic information encoded in DNA into messenger RNA (mRNA), it pauses shortly after starting. Known as promoter-proximal ...
When a gene is active, there is cellular machinery that transcribes the sequence of that gene from DNA into messenger RNA. This is a fundamental cellular process that is essential to the proper ...
A time-delay circuit enables precise control over the division of synthetic DNA droplets, which mimic biological Liquid-Liquid Phase Separation (LLPS) droplets found in cells. By utilizing a ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
