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 prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

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 ...

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 ...
