Two stories just published provide a much different picture of how bacterial cells continually repair lesions in their DNA. Led by researchers from the NYU Grossman School of Medicine, the work ...

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 ...

The study presents a new mesoscopic (i.e., between microscopic and macroscopic) simulation model of DNA movement. This new model is essential to optimise research in the field of nucleic acids ...

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 new model offers a possible solution to the scientific question of why neutral sequences, sometimes referred to as 'junk DNA', are not eliminated from the genome of living creatures in nature and ...

Researchers have modeled a key mechanism by which DNA replicates. The study could help identify new targets to treat disease. Knowing the structure of a complex biological system isn't nearly enough ...
