Solution:
Escherichia coli is a bacterium that is rod-shaped and Gram-negative. It belongs to the genus Escherichia and the most widely studied prokaryotic model organism. This bacterium is mostly used in biological research for its minimal living requirement. This allows it to be cultured easily and manipulated as per the requirements making it inexpensive for lab purposes. The plasmid is used as a cloning vector in the genetic engineering process.
