bacterial reproduction

Hi Friends!!!

Why do we fall sick?

Our body is under constant attack by small & tiny organisms called the germs which causes infection & we fall sick.


Let us learn about bacterial reproduction


Bacteria are one of the germs which cause infection. Bacteria are prokaryotic organisms which reproduce asexually. Bacterial reproduction most commonly takes place by a kind of cell division said to be as binary fission. Binary fission results in the formation of 2 bacterial cells which are genetically identical.

Bacterial reproduction most commonly takes places by a kind of cell division is said to be as binary fission. Binary fission results in the formation of 2 bacterial cells that are genetically identical. During binary fission the single DNA molecule replicates & both copies attach to the cell membrane. The cell membrane begins to grow between the 2 DNA molecules. Once the bacterium just about doubles its unique size the cell membrane begins to pinch inward. A cell wall then forms between the 2 DNA molecules dividing the original cell into two identical daughter cells.

In our next blog we shall learn about law of conservation of energy I hope the above explanation was useful.Keep reading and leave your comments.
