Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

CRISPR/Cas was first discovered in prokaryotes (bacteria and other single-cell organisms that lack nuclei) and scientists including Zhang's lab have long wondered whether similar systems exist in ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

Archaea and bacteria are two different domains of cellular life. They are both prokaryotes, as they are unicellular and lack a nucleus. They also look similar (even under a microscope). However, DNA ...

Alternative splicing exhibits lineage-specific variability, with mammals and birds reaching the highest levels despite conserved intron-rich architectures, while unicellular eukaryotes and prokaryotes ...

Limnology and Oceanography, Vol. 59, No. 3 (2014), pp. 972-985 (14 pages) Taxon-specific nitrogen (N) isotope data from the summertime Sargasso Sea have previously suggested reliance of prokaryotic ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. A team of researchers has uncovered a new biological editing system ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...
