genetic engineering DNA fingerprinting cloning of organisms antibody therapy
I gave my students this multiple choice question: For centuries, farmers have been taking cuttings of productive plants and rooting the cuttings to make new plants. Which kind of modern technology uses genetic information most similarly to the cutting and rooting process?

Only one answer is correct among these 4 choices:
- genetic engineering
- DNA fingerprinting
- cloning of organisms
- antibody therapy

Could you tell me which one is correct?

cloning of organisms
