This closeness allows prokaryotic cells to rapidly respond to environmental change by quickly altering the types and amount of proteins they manufacture. Note that eukaryotic cells likely evolved ...

Eukaryotic cells also contain a variety of structures and organelles not present in prokaryotic cells. Throughout the course of evolution, organelles such as mitochondria and chloroplasts (a form ...

While the endosymbiotic theory is widely accepted, the billions of years that have passed since the fusion of an Archaea and ...

4 As researchers continue to refine models of eukaryogenesis, it is becoming increasingly clear that the transition from prokaryotic to eukaryotic life was not a singular event but a complex, dynamic ...

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.
