Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have ...

A unique feature of HR is that it repairs the damage to the DNA in a highly accurate way. In eukaryotic cells (those with a nucleus), HR is performed by an enzyme called RAD51, which binds to ...

Using cutting edge cryo-electron microscopy ... showing how this molecular motor methodically separates the DNA double helix. It's like a molecular-scale zipper in action and while scientists ...

Using cryo-electron ... know how DNA, helicases and ATP work together in a coordinated cycle to drive DNA unwinding," De Biasio said. When Watson and Crick reported the double helix in 1953 ...

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.

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

Many cellular core components, such as DNA, RNA, proteins and lipids, are just a few nanometers in size. This makes them substantially smaller than the resolution limit of traditional light microscopy ...

Picoviruses always kill the cells they infect, after binding to the bacterial cell wall, enzymatically breaking through that wall, penetrating the cell membrane and injecting viral DNA into the ... of ...

One of the first biological molecules characterized by atomic force microscopy (AFM) was DNA ... to resolve the two oligonucleotide strands of the Watson-Crick double helix for single DNA molecules ...

But to Paul Mischel, the fuzzy dots he saw under the microscope offered a tantalizing ... We now know that ecDNA isn’t just a naked DNA double helix. Our cells organize DNA by wrapping it ...

DNA usually forms the classic double helix shape discovered in 1953 - two ... method of visualising the new fluorescent marker with microscopy. He said: "Scientists need special probes to see ...
