What is genetic engineering?

• A. Branch of Bio tech that uses special procedures and techniques to change an organism's DNA
• B. The study of ancient organisms
• C. The process of photosynthesis in bacteria
• D. The use of chemicals to alter organ systems

Answer: (A)

Genetic engineering is about using specialized lab techniques to alter an organism’s DNA. Scientists cut, insert, or edit genetic material to change how genes work or to introduce new genes from other organisms, enabling traits like disease resistance, improved crops, or production of useful medicines. This relies on methods such as recombinant DNA technology and gene editing with tools like CRISPR, which directly modify the genetic instructions. The other options describe areas that aren’t about changing DNA—studying ancient organisms is paleontology, photosynthesis is a metabolic process, and changing organ systems with chemicals isn’t about DNA modification. So the best description is the branch of biotech that uses specific procedures to change an organism’s DNA.
