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

As in prokaryotes, eukaryotic repressor molecules can sometimes bind to silencer elements in the vicinity of a gene and inhibit the binding, assembly, or activity of the transcription complex ...

Scientists propose that the eukaryotic branch of this family tree formed when two prokaryotes, an ancient bacterium and archaeal cell, merged, forming a symbiotic relationship maintained over time. 1 ...

Most cells grow, perform the activities needed to survive ... In contrast to prokaryotic cells, eukaryotic cells may divide via either mitosis or meiosis. Of these two processes, mitosis is ...

2 However, new findings suggest that the origins of eukaryotic complexity may be more nuanced than the traditional endosymbiotic model alone can explain. Some prokaryotes, such as planctomycetes, ...

“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, ...

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 more rings called plasmids.
