Prokaryotic Cells
|
A prokaryote is a single-celled organism that lacks a membrane-bound nucleus mitochondria, or any other membrane-bound organelle.
The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome . The nucleoid and some other frequently seen features of prokaryotes are shown in the diagram to the left, which shows a cut-away of a rod-shaped bacterium. Some prokaryotic cells have external whip-like flagella for locomotion or hair like pili for adhesion. Prokaryotic cells come in multiple shapes: round, rods, and helical cells. Prokaryotes reproduce asexually by binary fission; they can also exchange genetic material by transformation, transduction, and conjugation. |
