Binary Fission

• Binary Fission only occurs in Prokaryotic cells
• Binary fission stages- 1. Cell grows

  2. Cell replicated genetic material

  3. DNA is split and pulled to opposite end of cell

  4. PLASMIDS ARE ARRANGED RANDOMLY

  5. grow cell wall and membrane in middle

  6. cell is split and pulled apart
• A Bacterial cell has a mean division of 30 mins

  how many bacterial cells are there after 3 hours?

  3 hrs=180 mins

  180/30=6 rounds of division

  1x26= 64 bacterial cells
• what affects binary fission/ what improves the rate?

  temperature, moisture, nutrients
• Bacteria multiply by Binary fission(original amount of bacteria)x2n n being your amount of time/ division time
• Binary fission equation that bacteria uses

  (original amount of bacteria)x2 to the power of n n being your amount of time/ division time
• We make cultures with what techniques?

  Aseptic techniques
• What is the inhibition zone

  area in which bacteria did not grow, use pi r2
