Medical Definition of Cloning vector
1.
A DNA molecule originating from a virus (plasmid vector), or the cell of a higher organism into which another DNA fragment of appropriate size can be integrated without loss of the vectors capacity for self- replication.
Vectors introduce foreign DNA into host cells, where it can be reproduced in large quantities. They are also used to insert DNA from one cell type to another.
Examples are plasmids, cosmids, and yeast artificial chromosomes, vectors are often recombinant molecules containing DNA sequences from several sources.
Cloning vectors are usually designed to have convenient restriction sites that can be cut to generate sticky end to which the DNA that is to be cloned can be ligated easily.
