Why plasmid is important in biotechnology?

Genetic Engineering is the technique of transferring a DNA with a specific gene from an organism to the desired organism. The process requires a vector through which the gene of interest can be transferred from one organism to another organism. Usually desired genes are integrated within the chromosome of vectors. Vectors will express the gene of interest in the target population. Plasmids are such vectors, which carry the gene of interest from one organism to another organism and make the recombinant technology easier.
