The trunk of each 'Christmas tree' (a transcription unit) represents a DNA molecule; the tree branches (granular strings attached to the DNA) are RNA molecules that have been transcribed from the DNA.

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged. Cellular DNA is continuously exposed to both ...

By Knvul Sheikh Peering inside cells has been an integral part of biology ever since the 17th century, when cells were discovered under a microscope. But even with advances in light and electron ...

They also note that nucleosomes can fold into other helical structures under ... other DNA-related biological processes. Here, we report the 11-angstrom–resolution cryogenic electron microscopy ...

but this bunched-up state is visible under a microscope. With an electron microscope, you can zoom in even more, and at this resolution it’s possible to see a strand of DNA in a cell.

When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to ... and snippets of DNA. It's a more useful way to size soft objects like proteins that can be clumped, stringy ...

which is more compact than normal DNA. Using cryo-electron microscopy (cryo-EM), a team of structural and molecular biologists at Memorial Sloan Kettering Cancer Center (MSK) set out to investigate ...

(Nanowerk Spotlight) Applications and studies in DNA-based biophysics, biochemistry and biotechnology rely on accurate imaging with high temporal and spatial resolution towards the mesoscopic and ...

A research team from Skoltech, the Institute of Physical, Chemical, and Biological Problems of Soil Science of the Russian Academy of Sciences, and other scientific organizations in Russia and the U.S ...

In 2017, Luger and her colleagues discovered that archaea — microbes that resemble bacteria under the ... to their spooled DNA. Using computer simulations and electron microscopy experiments ...
