In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive organelles, such as micro-compartments found in some bacteria, help organize cellular processes by concentrating ...

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique ...

Planctomycetes challenge our concept of the bacterial ... the Eukaryote-Like Cell Biology of a Bacterium Planctomycete cell structure differs from that of all other known prokaryotes.
