The vectors are DNA molecules that can carry a foregin DNA segment and replicate inside the host cell. One amongst the following is not used as a vector in recombiant technology :

The proof for semiconservative mode of DNA replication was First provided by Matthew Meselson and Franklin Stahl. Escherichia coli were the first organism to be used for this experiment and then it was done in with higher organisms such as plants and human cells.
