Which of the following most used in genetic engineering?
Mycobacteria and Salmonella
The correct option is A E.coil and Agrobacterium
Genetic engineering is a branch of science that uses various biotechnological techniques to manipulate an organism's genome to create species with desired traits. However, the process involves isolation, transfer and insertion of the new genetic material into host genomes and storage of genomes in organisms and selective markers for an indefinite period. Experiments have shown that certain bacteria has the ability to naturally take in and express foreign DNA. It has been found that of these, E.coli has the ability to transfer DNA laterally to and from other species while Agrobacterium can transfer genes to plants and fungi by causing crown gall disease.
