Which one of the following options is NOT an example of genetic engineering?
Correct answer: C. Photosynthetic bacteria
- A. Insulin-producing bacteria
- B. Oil eating bacteria
- C. Photosynthetic bacteria
- D. Metal extracting bacteria
Explanation
For bacterias to be photosynthetic they do not need to be genetically programmed. There are naturally occurring photosynthetic bacterias. But, other bacterias such as insulin-producing, oil-eating, and metal extracting ones are those that do not occur naturally; they need to be genetically programmed to do so.
