Prokaryotic Cell Division: Binary Fission Mechanism

Prokaryotic cells undergo division through binary fission, where a membrane forms to divide their cytoplasm in two. Replication of the single circular DNA molecule occurs before cell division, leading to the formation of daughter cells. The process involves DNA replication, cell growth, and membrane separation, resulting in the creation of two daughter cells.

Presentation Transcript

  1. 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.

  2. The chromosome of prokaryotic cells is a single circular DNA molecule running throughout the cytoplasm. DNA molecule DNA molecule • Replication of the DNA molecule occurs before cell division. Plasma membrane Cell wall DNA molecule formed by replication • 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.

  3. 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
