Today, recombinant DNA technology enables precise gene manipulation, creating genetically modified organisms (GMOs) with enhanced traits. While offering benefits like robust crops and new medicines, it raises bioethical concerns, especially regarding human genome modification.

The bacteria replicate the gene and can produce proteins, such as insulin. Antibiotic resistance genes in plasmids help select bacteria containing the desired gene.
