binary fission Flashcards
1
Q
what is binary fission?
A
binary fission is where the cell splits into two
2
Q
step one?
A
the circular DNA and plasmids replicate
3
Q
step two?
A
the cell gets bigger and the circular DNA strands move to opposite ‘poles’ (ends) of the cell
4
Q
step three?
A
the cytoplasm divides and the two daughter cells and produced, each daughter cell has one copy of the circular DNA but can have a variable number of copies of the plasmids
5
Q
can bacteria divide? and what will they need
A
bacteria can divide very quickly when given the right conditions- warm environment and lots of nutrients
6
Q
how can you calculate the number of bacteria in a population?
A
the mean division time is the average amount of time it takes for one cell to divide into two.
