What are different stages of binary fission?
Answers
Step 1 REPLICATION:
The bacteria makes a duplicate of its DNA. This DNA carries all the instructions for the new cell about it's mission(making your throat sore for instance!).
To get into the nitty gritty of how replication happens, this cool animation will be useful.

Step 2 GROWTH:
The parent cell becomes considerably larger in size and the two DNA copies begin moving away from each other.

Step 3 SEGREGATION:
The cell becomes longer and the cell membrane pinches inwards from the middle, with the two DNA at opposite poles of the cell.

Step 4 DIVISION
A cleft forms in the middle and the parent cell splits into two identical daughter cells, each with its own DNA.

The outcome of binary fission is two daughter cells which are genetically identical.
Some bacteria divide every 30 minutes. You may wonder how do they get to be so many at this rate? Well, this is where the mind blowing concept of exponential growth and natural log (e) applies. Over here. This is how bacteria get so much so fast.
If you found this process fascinating (which it is considering its happening right nowinside all of us ), you can explore it even more and gain a deeper understanding of it through this animation:
