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 ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key ...

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 ...

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 ...

The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

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 ...

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 ...

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 ...

Fusion oncoproteins arise when a gene fuses with another gene and acquires new abilities. Such abilities can include the ...
