For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation is the first step in DNA replication. This breakthrough, published ...

which is more compact than normal DNA. Using cryo-electron microscopy (cryo-EM), a team of structural and molecular ...

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.

An international team of microbiologists from the Medical University of Graz, the DSMZ—German Collection of Microorganisms ...

Chromatin remodeling plays a vital role in gene regulation, affecting how DNA is accessed. Disruptions in this process can ...

A single DNA nucleotide, the base unit of the human ... it much too small to be identified by even the most powerful electron microscope. So how, then, do researchers determine the sequence ...

Scientists at the University of Iowa have made an exciting discovery that could lead to new cancer-fighting drugs. They found ...

Using cutting edge cryo-electron microscopy, the team of scientists were able to visualise a helicase enzyme (nature's DNA unzipping machine) in the process of unwinding DNA. DNA helicases are ...

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 ...

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 ...

The limit of resolution of the transmission electron microscope is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope.
