Genetic engineering of plants, animals and microorganisms such as bacteria typically involves the use of restriction enzymes to 'cut and paste' DNA fragments into certain genetic sequence locations. This process allows scientists to introduce new genes into an organism, but is constrained to specific recognition sequences, limiting the design of recombinant DNA molecules.
