Researchers have discovered how the protein XPD detects severe DNA damage and controls its repair. The XPD protein is a central component of our body's own "DNA repair team," known as nucleotide ...

Using cryo-electron microscopy (cryo-EM), a team ... G-quadruplexes and Cancer "The DNA double helix is one of the most recognizable molecular structures in science," Dr. Batra says.

This organization can be explained by weak interactions between nucleosomes, which are the repetitive blocks that fold the ...

The process of transcription can be visualized by electron microscopy (Figure 1 ... Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand ...

Watson and Crick ultimately used Franklin's images, along with their own evidence for the double-stranded nature of DNA, to argue that DNA actually takes the form of a double helix, a ladder-like ...
