In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling, this complex can be "opened" so that specific genes are expressed. Various molecules ...

It may look alien, but this protist could tell us about our origins right here on Earth.

Nuclear magnetic resonance measurement and state-of-the-art computational science reveal protein structures in higher eukaryotic cells. Researchers from Tokyo Metropolitan University have successfully ...

Previously, chemists have managed to create artificial cell walls and developed synthetic DNA to produce self-replicating, synthetic bacterial cells. Now, for the first time, researchers have used ...

An exchange of genetic material that occurred when ancient giant viruses infected ancient eukaryotic cells could have caused the nucleus of the eukaryotic cell -- its defining feature -- to form. A ...

Bacteria are different from you and me. Always the minimalists, they lack features that plant and animal cells usually can’t do without: a nucleus, special organelles, and an internal skeleton made of ...

Molecular biology has something in common with kite-flying competitions. At the latter, all eyes are on the colorful, elaborate, wildly kinetic constructions darting through the sky. Nobody looks at ...

All three RNAPs have catalytic cores consisting of 10 subunits. Five of these are core subunits which form crab claw shapes with DNA at their centres, channels for RNA products and NTP substrates as ...

Under a microscope, the newly described organism Solarion looks less like a cell and more like a tiny star, its body ringed ...
