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 ...

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 ...

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 ...

In both physics and chemistry, the mesoscopic scale refers to the length scale on which the properties of a material or phenomenon can be studied, without entering into a discussion about the behavior ...

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 ...

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 ...

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 ...

We propose a DNA-hairpin model for the processivity of telomeric-repeat addition. Concomitantly with template-RNA translocation after each repeat synthesis, the complementary DNA repeat, for example, ...
