Mention two uses of cloning vector
Answers
In general, cloning vectors are plasmids that are used primarily to propagate DNA. They replicate in E. coli to high copy numbers and contain a multiple cloning site (also called a polylinker) with restriction sites used for inserting a DNA fragment. ... An expression vector is a specialized type of cloning vector.
Answer:
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).
