According to scientists, the world is split into two kinds of organisms — prokaryotic vs. eukaryotic — which have two different types of cells. An organism can be made up of either one type or ...

Results reported in a recent Science paper provide the first experimental evidence to support the hypothesis that prokaryotes possess a defence system that might be analogous to eukaryotic RNA ...

Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles ...

The first phase of the MEER research was a joint effort of Shanghai Jiao Tong University, the Institute of Deep-sea Science ...

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey Palmer of Indiana University, Bloomington, ...

As an agent, your first responsibility is to identify the league for which your particular client (protein) is best suited. There are, of course, the standard prokaryotic, yeast and mammalian leagues.

Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings called plasmids.

Genetic switches could play a role in creating complex eukaryotic genetic circuits for programmed cell-free systems or artificial cells.

Organisms known as extremophiles have been found inhabiting a range of extreme conditions on Earth, including inside our ...

Aude Bernheim is a microbiologist studying how bacteria defend against viruses. She earned her PhD at the Pasteur Institute in Paris, researching CRISPR-Cas evolution, and completed a postdoc at the ...
