Explain how poor aseptic technique during bacterial isolation could eventually affect medical research results.
Contamination could produce inaccurate conclusions and unreliable data.
Compare PCR and bacterial cloning as methods of producing large amounts of DNA.
PCR amplifies DNA quickly in vitro; cloning uses living bacteria to replicate DNA.
Explain why biotechnology requires BOTH ethical guidelines and laboratory safety procedures.
Ethics protect society and individuals; safety protects workers and environments.
Predict what would happen if antibiotics were overused globally for many years.
