What is involved in creating genetically modified bacteria?

• A. Allowing them to reproduce freely
• B. Changing their food source
• C. Using biotechnology techniques
• D. Growing them on selected plants

Answer: (C)

Creating genetically modified bacteria involves using biotechnology techniques to alter their DNA. Scientists insert or edit genes, often using a carrier molecule like a plasmid, and then use methods to identify and grow only the bacteria that carry the desired genetic change. This process is what changes the bacteria’s traits, such as producing a useful protein or functioning in a new environment. Simply letting bacteria reproduce freely isn’t about making targeted genetic changes. Changing what they eat doesn’t modify their DNA, and growing bacteria on plants describes a different context not involved in making GM bacteria. So the essential idea is applying biotechnology tools to modify the bacteria’s genetic material.
