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 ...

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 ...

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 ...

A DNA profile is often important evidence in cases of rape or other sexual assault of women, but if investigators have only scant biological material, the results may be difficult to interpret and use ...

The human body is a remarkably complex machine, so it would make sense that it houses an abundance of DNA – the blueprints that help guide the body's growth and repair. But how much DNA do our bodies ...

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 ...

Anthropologist Carla Handley is sitting cross-legged in a mud-walled house in a Kenyan village called Merti. She's meeting with a man dressed in a flowing blue robe and a woven cap of red and white.
