1. UNIT 2 Genetic information Biology and Geology 4. Secondary Education CELL DIVISION IN PROKARYOTIC CELLS

2. UNIT 2 Cell division in prokaryotic cells Biology and Geology 4. Secondary Education. Prokaryotic cells have a mechanism for division known as binary fission, which consists of the formation of a membrane which divides their cytoplasm in two.

3. UNIT 2 Cell division in prokaryotic cells Biology and Geology 4. Secondary Education. The chromosome of prokaryotic cells is a single circular DNA molecule running throughout the cytoplasm. DNA molecule Plasma membrane Cell wall Replication of the DNA molecule occurs before cell division. The cell increases in size and a cell plate is formed on the inside of the plasma membrane. Each DNA molecule joins at a different point. DNA molecule DNA molecule formed by replication

4. UNIT 2 Cell division in prokaryotic cells Biology and Geology 4. Secondary Education. The membrane plates pull the DNA molecules apart and separate them. The membrane keeps growing until complete separation takes place, giving rise to two daughter cells. Daughter cells
