Plasmid is a boon of biotechnology. Justify this statement.

Plasmid is a boon of biotechnology:

Plasmid are small circular DNA found in bacteria. These are used as vector in transporting gene inside bacteria with the purpose to create Recombinant DNA inside the bacteria. For this purpose the plasmid is down out,a part of the plasmid DNA is removed by endonuclease and in that part  another part of Desired DNA part collected from another organism is inserted using ligase. This plasmid is then allowed to enter the bacterial cell and carry out recombination process. Plasmid therefore plays a vital role in DNA recombination Technology without which it would have been impossible to carry out genetic engineering. It's therefore an important tool in genetic engineering.
