In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in ...

DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. Scientists have found a flaw in the most common model for DNA elasticity, a discovery that ...

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 ...

As illustrated with OnScreen Gene Transcription in our May 1 column, OnScreen Science now has a few very nice iPad apps to teach students about DNA and RNA. The OnScreen DNA Model app was the original ...

April 23 (UPI) --Scientists have for the first time created a billion-atom biomolecular simulation. Researchers designed the computer model to simulate a single DNA gene. The feat, described this ...

This is a stunning 3D map that shows how six feet of of DNA can be crammed inside a single chromosome — a space that’s only a hundredth of a millimeter across. Not surprisingly, it looks like ...

In a new study, researchers reveal how an enzyme called RNA polymerase patrols the genome for DNA damage and helps recruit partners to repair it. The result: fewer mutations and consequently less ...

Student teams investigate a fictional anthrax case by modeling DNA sequencing and tracking down the "guilty" lab. B. The science behind identifying the suspected lab In the anthrax case, the ...
