Genetic engineering is a highly sophisticated technique for artificial and deliberate modifying DNA to suit human needs. It may also be called as cloning of genes and their propagation into the carrier. There are three important tools needed for genetic engineering; Enzymes, Vector and Passenger DNA. The different groups of enzymes involved in recombinant technology. Passenger is the complementary, synthetic or random DNA formed by breaking chromosome with the help of restricted endonuclease. Vector DNA is used to transfer passenger DNA to a suitable host. However, in some cases, gene transfer can occur directly without involving a vehicle.
