In 1970, hamilton smith isolated the first restriction enzyme. restriction enzymes are used to cut strands of dna at specific
points. this discovery led to the development of recombinant dna, which is widely used in several scientific industries to

knowledge caused by smith's discovery most directly affected which sector of society?
o technology
o commerce
o government
