When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

Neuroscientists have uncovered a new mechanism for memory formation, and it involves changes in the structure of your DNA. If you were asked to picture a molecule of DNA, chances are you would ...

The formation of four-stranded DNA has been tracked in living human cells, allowing scientists to see how it works, and its possible role in cancer. DNA usually forms the classic double helix shape ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term ...

This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

We are exposed to ionizing radiation more often than we think: when we bathe in the sun, which emits UV rays, or when we get X-rayed. Even when we are travelling on an intercontinental flight, which ...

Students take samples of water and the microscopic creatures within at the Alviso Marina County Park. (Image by Erika Cardema) At the Alviso Marina County Park, reddish-brown water laps at the edge of ...
