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 ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

Previous researches on DNA included topics of bases, base-pairing, hydrogen bonds, structure, base sequence, dynamics, ...

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 study has revealed that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate. Cell division is fundamental for life, allowing organisms to ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

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 ...

In a remarkable fusion of biology and technology, a DNA-based computer that performs effectively has been created by ...

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.
