4A The Prokaryotic Cell Cycle

Question 1

Define Binary Fission/Purpose/e.g.

Answer 1

• A type of asexual reproduction (method
  of reproduction that produces
  genetically identical cells without
  the fusion of gametes) That Prokaryotic Cells use to replicate + reproduce
• Fast Process (exponential growth) (Bacteria doubles in size every 20 minutes)

Question 2

Identify + outline the 6 stages of Binary Fission

Answer 2

1. Prokaryotic cell before replication (one parent cell)
2. Circular Chromosomes - uncoil + DNA and Plasmid replicates
3. Cell elongation (cell extends in size + duplicated chromosomes and plasmid move to opposite sides of the cell)
4. Cytokinesis (a septum is created)
5. New Cell wall + membrane formed
6. Two genetically identical daughter cells formed
