Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules.

A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause ...

Ribonucleic acid (RNA) is one of life's most versatile molecules, with roles going far beyond being a messenger of genetic ...

Google DeepMind has expanded its AlphaFold AI system to not only predict the structure of proteins, but also to model how proteins interact with other cell structures, including DNA, RNA, and small ...

RNA’s Surprising Role in DNA Repair New insights could lead to improved treatments for cancer and other diseases. Francesca Storici and her research team discovered a surprising role for RNA in DNA ...

A team of scientists that included researchers from UCLA has discovered a novel mechanism of RNA regulation in embryonic stem cells. The findings are strong evidence that a specific chemical ...

Scientists for the first time have found strong evidence that RNA and DNA could have arisen from the same set of precursor molecules even before life evolved on Earth about four billion years ago.

If you thought that the RNA world hypothesis had comfortably eclipsed the DNA world hypothesis, think again. As far as molecular biologists at the MRC Laboratory are concerned, the two hypotheses are ...

Key building blocks of DNA and RNA can be made from the same raw materials. This finding suggests that instead of one or the other kick-starting life on Earth, both chemicals were involved in the ...
