Question

Mention the uses of cloning vector in biotechnology.

Answer 1

A cloning vector is DNA taken from a virus, plasmid or cells to be inserted with a foreign DNA fragment for cloning purposes. They often carry antibiotic resistance genes that can be used to test for expression of the plasmid DNA, on antibiotic petri plates. In other words, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated and/or expressed (e.g.- plasmid, cosmid, Lambda phages).
