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 ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

In contrast, the DNA of prokaryotic cells is distributed loosely around the cytoplasm, along with the protein synthesis machinery. This closeness allows prokaryotic cells to rapidly respond to ...

Protein synthesis refers to the process by which cells construct proteins. It's a fundamental cellular mechanism for all living organisms, as proteins carry out enzymatic activities, structural ...

“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, ...

Eukaryotic cell DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or ...

The International Committee on Systematics of Prokaryotes recently pulled the rank of phylum into its code of official nomenclature. Experts say the move will help standardize science in the long run ...

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