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.

Until now, this was only possible using expensive structural biology methods such as electron ... With ONE microscopy, the first individual images of the entire molecule are available less than ...

improving the lateral resolution of side-by-side features in images of the DNA molecule. WASHINGTON, Jan. 14, 2025 – Most microscopes can only illuminate objects down to a certain size before ...

In all living organisms, DNA contains the code that defines ... because such studies relied on techniques like cryo-electron microscopy, which require frozen samples, thus only providing snapshots ...

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

Rock and dust samples brought back to Earth from the asteroid Bennu contain organic matter and a variety of minerals crucial to the emergence of life ...

There's three types of microscope: light, like this one here, and two types of electron microscopes, like those ones over there. Light microscopes use light and mirrors and can see things as small ...

Most microscopes can only ... for stretching and immobilizing DNA with minimum thermal fluctuation to enable detailed analysis. "Immobilizing the molecule essentially 'glues' it to a substrate ...

A team at Nagoya University experimented with ways to uncurl a DNA molecule using pressure applied ... of the stretch ratio of the DNA. Most microscopes can only illuminate objects down to a ...
