In the recombinant DNA technology, the DNA segment also called the vehicle DNA that carries the foreign DNA to the host is called a vector. These are the DNA molecules that transfer the desired genetic material into another cell. The vectors are capable of self-replication in the host cells. The commonly used vectors are plasmids, bacteriophage DNA, cosmids, etc.
