GCSE AQA Biology Paper 1

• Bacteria are prokaryotes, their genetic information is not enclosed in a nucleus
• Binary fission

  The process where one bacterial cell splits into two bacterial cells
• Bacteria can carry out binary fission once every 20 minutes as long as they have enough nutrients and the temperature is suitable
• Calculating the number of bacteria after a given time

  1. Calculate the number of rounds of division

  2. Use the equation: Number of bacteria = 2^n, where n is the number of rounds of division

  3. Express the answer in standard form (if required)
