Binary fission Flashcards
1
Q
In what types of cells does binary fission occur
A
- Prokaryotic cells (bacterial cells)
2
Q
What can binary fission also be referred to
A
- Asexual reprodction
- Method of cell division
3
Q
What different organelles does a prokaryotic cell contain
A
- Cell wall
- Plasmids (non-essential DNA)
- Free-flowing cicular DNA (essential DNA)
- Cytoplasm
- Cell membrane
4
Q
Explain the stages of Binary fission
A
- Cell grows in size (more space for replication)
- Circular strand of DNA and plasmids replicate
- Circular strand of DNA go to opposite sides of the cell. Plasmids are arranged randomly
- New cell wall grows down the middle
- Cell splits into 2 daughter cells
- Each cell may have different number of plasmids
5
Q
What are the perfect conditions for binary fission
A
- Warm
- Available nutrients
- Moist
6
Q
What is the mean division time
A
- Average amount of time for 1 bacterial cell to replicate into 2
7
Q
What is the difference between plasmids and circular strand of DNA
A
- Plasmids are non-essential DNA
- Circular strand of DNA are essential DNA
