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 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.

For example, regions of the genome that are rich in guanine bases (represented by G in the DNA code) can fold into a DNA structure called a G-quadruplex, or G4 for short, which is more compact than ...

The coiled telephone cord and the DNA double helix that stores the genetic material ... DNA minicircles using recent technology advances in electron cryomicroscopy, an imaging technique that ...

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 ...

THIS YEAR, though, Holmes and Bate entered the field with a potentially powerful new research tool at their fingertips, environmental DNA, or eDNA. With just a small sample of water, the duo hopes ...

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 ...

It’s called cryoelectron microscopy ... for figuring out the structure of proteins and DNA was X-ray crystallography. This led to many breakthroughs — including the discovery of the DNA double helix ...
