NASA scientists found amino acids, key minerals, and nucleobases for DNA in samples from the OSIRIS-REx asteroid mission.

In bacteria, researchers have long known that transcription begins when RNAP clamps onto a DNA strand and initiates ... and twisted form of the double helix—because it better mimics the natural ...

Pasta shapes like penne, rigatoni, and cavatappi owe their existence to a combination of technological innovation and ...

The initial structures of the short DNA helix segments are not critical to the simulations ... and thermal fluctuations during the double strand separation. One additional goal is to establish force ...

Winged helix (wH) domains, also termed winged helix-turn-helix ... which cooperate to position an endonuclease dimer for a double strand (ds) cut in the DNA. Fully modified = M+ top/M+ bottom = M+/M+.

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

Cohesin plays a crucial role in both chromosome organization and DNA repair. Here the authors find that cohesin mediated genome architecture prevents interactions between damaged chromatin.
