Vedclass · Answer

(D) Genetic engineering,or recombinant $DNA$ technology,relies on the ability to manipulate $DNA$ molecules.Restriction endonucleases are enzymes that act as 'molecular scissors' by cutting $DNA$ at specific recognition sequences.These enzymes were originally discovered in bacteria,where they serve as a defense mechanism against bacteriophages.By purifying these enzymes from bacteria,scientists can use them in the laboratory to cut $DNA$ at precise locations,which is the fundamental step in creating recombinant $DNA$ molecules.
