Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated ...

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus ...

It's a fundamental cellular mechanism for all living organisms, as proteins carry out enzymatic activities ... Comparing ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged.

Research from the University of Jena reveals that certain prokaryotes, specifically planctomycetes, can consume other cells, contradicting previous beliefs that only eukaryotes could perform ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

Calcium signaling plays a vital role in both eukaryotic and prokaryotic cellular processes, but the mechanisms behind calcium transport are more thoroughly understood in the former. Burgeoning ...

For most genes, proteins are the athletic embodiment of these professional activities. Our task as agents then ... There are, of course, the standard prokaryotic, yeast and mammalian leagues. Within ...

Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings ...
