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 ...

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 ...

Cells contain a blueprint in the form of DNA that dictates what they can make. This blueprint is converted into a message ...

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 ...

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 ...

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.

DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

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 ...
