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.

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

Ultrafast electron microscopes, first developed in the 2000s ... the electrons move and control them on demand to confirm the DNA 3D structure. This, indeed, will open the door for more scientific ...

"Electron microscopy is a crazy, cool technique," Philipp Haslinger, Associate Professor at the TU Wien, says. "In principle, we could use it to look at the spike proteins of a virus or its DNA ...

MSK researchers are helping to map the landscape of viruses that infect us all, and to analyze the impact they have on human health and disease.

If DNA is a book, then how is it read? Learn more about the DNA transcription process, where DNA is converted to RNA, a more portable set of instructions for the cell. The process of transcription ...

Using cryogenic electron microscopy, Partho Ghosh's lab at UC San ... The red RNA ribbon is the segment that is reverse-transcribed back to DNA. Credit: Partho Ghosh lab / UC San Diego These ...

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 ...
