WHAT OCCURS DURING PROKARYOTICCELL CYCLE?

1. The usual method of prokaryote cell division is termed binary fission.

2. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane.

3. When the cell begins to pull apart, the replicate and original chromosomes are separated.

4. The prokaryotic cell cycle consists of a relatively long period of growth, during which the cell replicates it's DNA, followed by a type of cell division called prokaryotic fission.

5. The prokaryotic chromosome is usually attached at one point to the inside of the plasma membrane of the cell.

6. During the growth phase of the prokaryotic cell cycle, the DNA is replicated, producing 2 identical chromosomes that become attached to the plasma membrane.

7. As the cell grows, new plasma membrane is added between the attachmet sites of the chromosomes, pushing them apart.

8. When the cell has doubled in size, the plasma membrane grows inward between the two attachment sites.

9. The plasma membrane then fuses along the equator of the cell, producing two daughter cells, each containing one of the chromosomes.

10. The two daughter cells are genetically identical to one another and to the parent cell.
