Binary Fission Flashcards
(10 cards)
What type of cells use binary fission?
Prokaryotic cells e.g. bacteria
What is binary fission?
A means of asexual reproduction or cell division
What are plasmids?
They are circles of DNA which contain non essential genes.
Process of binary fission
1
The genetic material (chromosomal DNA (Circular DNA) and plasmids) is replicated
2
The cell expands and the circular DNA moves to opposite poles of the cell and the plasmids are arranged randomly on either side (no set amount of them)
3
The cytoplasm begins to divide and new cell walls begin to form
4
Once the cell wall is complete and the cytoplasm divides, 2 daughter cells are produced - each daughter cell will have one copy of the chromosomal DNA however the amount of plasmids will be random (a variable number)
What type of reproduction is binary fission?
its a type of asexual reproduction for cells as well as a type of cell division
How often do bacteria multiply by binary fission given they have enough nutrients and a suitable temp?
Bacteria multiply by binary fission as often as once every 20 minutes if they have enough nutrients and a suitable temperature.
