- Bacteria
- Viruses
- Humans
- Fungi
Correct

During division by binary fission the two copies of the circular DNA are attached to which structure?
- The cell membrane
- The ribosome
- The flagella
- The spindle assembly
Correct
Incorrect
Question 6 of 20
6. Question
The two copies of circular DNA are separated by what process during binary fission in prokaryotes?
- Cell growth
- Microtubule depolymerisation
- Kinesin movement along microfilaments
- Brownian motion
Correct
Incorrect
Question 7 of 20
7. Question
Binary fission of a parent cell results in how many daughter cells?
- 2
- 1
- 4
- 3
Correct
Incorrect
Question 8 of 20
8. Question
In most cases, binary fission results in which of the following?
- Two daughter cells with an exact copy of the DNA of the parent cell
- Two daughter cells with half of the DNA content of the parent cell
- Four daughter cells with half of the DNA content of the parent cell
- Four daughter cells with an exact copy of the DNA of the parent cell
Correct
Incorrect
Question 9 of 20
9. Question
Why might the genetic content of a daughter cell differ from a parent cell after binary fission?
- Mutation
- Replication
- Transcription
- Translation
Correct
Incorrect
Question 10 of 20
10. Question
Which of the following is true of binary fission?
- Plasmids are also replicated and distributed between each daughter cell
- Only the circular DNA is replicated and moved into each daughter cell
- The circular DNA is separated using spindle fibres
- Plasmids use flagella to swim into the new daughter cell
Correct
Incorrect
Question 11 of 20
11. Question
Why might the number of plasmids vary between each daughter cell following prokaryote cell division?
- Because the many plasmid floating in the cytoplasm are randomly segregated when the cell divides
- Because plasmids stay in the parent cell only
- Because there is only a single copy of the plasmid which stays in one of the daughter cells
- Because plasmids only ever occur in odd numbers, so one daughter will always inherit more
Correct
Incorrect

Question 15 of 20
15. Question
Which of the following prokaryotic features are not involved in cell division?
- Flagella
- Cell membrane
- Cell wall
- Plasmids
Correct
Incorrect
Question 16 of 20
16. Question
During binary fission, what happens after the cell membrane pinches inward and divides the cytoplasm in two?
- New cell wall forms between the two daughter cells
- Separation of the two copies of circular DNA begins
- Plasmids are moved along the cell membrane into each daughter
- The cell membrane forms a tube that connects the daughter cells
Correct
Incorrect
Question 17 of 20
17. Question
Explain why one daughter cell may not be antibiotic resistant following cell division in bacteria
- It may not have inherited any of the plasmids confering antibiotic resistance
- The antibiotic may have become more potent
- It may not have inherited a complete copy of the circular DNA
- It's cell wall may have reformed
Correct
Incorrect
