What is Binary fission

When one bacterial cell splits into two bacterial cells

2
New cards

When can Bacteria carry out binary fission

Once there is enough nutrients and the temperature is suitable

3
New cards

A type of bacteria divides every twenty minutes. Calculate the number of bacteria present after three hours

3 hours =180 minutes

180/20=9 rounds of division

Number of bacteria = 2Ă—2Ă—2Ă—2Ă—2Ă—2Ă—2Ă—2Ă—2=512

How does Binary fission work

1)DNA and plasmid replicate

2)Cell gets bigger and DNA strands move to opposite poles

3)The cytoplasm begins to divide and new cell walls form

4)Cytoplasm divides into two daughter cells each with one copy of circular DNA
