Vectors are carriers of DNA which are used to transfer gene of interest into host cell. Vectors used at present, are engineered in such a way that help easy linking of foreign DNA and selection of recombinants and non recombinants.

Ti plasmid is used vector for plant cell and retrovirus is used as a vector for animal cell.
