Binary fission
This is the process where prokaryotic cells replicate
...
Then
the cytoplasm begins to divide and new cell wall starts to
form
...


Bacteria divide
super fast when
in their
optimum
conditions
...
They are coiled up lengths of DNA
molecules
...
Body cells have 2 copies of each chromosome – 1 from the mother and 1 from the father
...


Culturing microorganisms
To grow bacteria in a lab will grow on agar plates which will display visible colonies on the surface
...
Once it
has set, using and inoculating loop you can transfer microorganisms to the culture medium (agar
plate) then a spreader can be used to get an even covering of bacteria
...
Within schools culture mediums cannot go above 25°C
...
To ensure that your results are exact you need to sterilise all your apparatus including
your hands to make sure no unwanted bacteria contaminate your test
...
The
chromosomes line up in the middle of
the cell and allow cell fibres to pull them
apart so that the 2 arms of each
chromosome go to opposite ends of the
cell
...
Then the cytoplasm and cell
membrane divide
...


In a cell the DNA is spread
out in long strings
...
The copied DNA
forms x-shaped
chromosomes and each
arm is an exact duplicate
of the other
...
At the end of the cycle the results are 2 new cells
that are identical to the original cell with the same number of chromosomes
