A step-by-step diagram shows donor DNA and vector DNA cut with restriction enzymes to create overhangs, mixed and sealed with ligase to form recombinant DNA, which is introduced into bacterial cells. The recombinant DNA replicates as the cells divide, producing clones. — biotechnology Steps involved in the engineering of a recombinant DNA molecule.

In the United States, living human-made microorganisms became eligible for patents following a landmark shift in 1980, when such organisms created through recombinant DNA technology were deemed patentable. This legal recognition acknowledges that genetically engineered microbes—which function as "chemical factories" to produce valuable substances like insulin—are distinct, human-invented products rather than mere naturally occurring phenomena.12

While this policy encourages innovation in biotechnology, it remains a subject of ethical debate. It is essential to uphold the principle that scientific progress must be balanced with rigorous safety oversight and public accountability. Concerns regarding corporate control, food security, and the potential environmental impact of genetically modified organisms (GMOs) highlight the necessity for transparent regulatory frameworks that prioritize the common good alongside commercial interests. As we continue to advance tools like CRISPR, maintaining a commitment to ethical standards is vital to ensure that these powerful technologies are used responsibly and for the benefit of society.1
