Vedclass · Answer

(D) Genetic engineering involves the manipulation of the genetic material of an organism using specific enzymes.Restriction endonucleases are enzymes that cut $DNA$ at specific recognition sequences.These enzymes were discovered in bacteria,where they serve as a defense mechanism against viral infection.By purifying these enzymes,scientists can use them in vitro to cut and join $DNA$ fragments,which is the foundation of recombinant $DNA$ technology.$Nathans$ and $Smith$ $(1970)$ isolated the first restriction endonuclease.$Jackson$,$Symons$,and $Paul$ $Berg$ $(1972)$ successfully generated recombinant $DNA$ molecules in vitro.
