The correct Answer is:
To determine how many of the statements are related to biotechnology, we will analyze each statement one by one. 1. **Statement A**: Development of pest-resistant crops by using RNA interference technique. - This statement is related to biotechnology. RNA interference (RNAi) is a technique used to silence specific genes, which can be employed to create pest-resistant crops. 2. **Statement B**: Development of milch breed of cow. - This statement is not related to biotechnology. The development of milch breeds typically involves traditional breeding methods rather than biotechnological techniques. 3. **Statement C**: Artificial selection in crops. - This statement is also not related to biotechnology. Artificial selection is a traditional breeding method where humans select for desirable traits in crops, which does not involve modern biotechnological techniques. 4. **Statement D**: Production of human insulin by use of bacteria. - This statement is related to biotechnology. The production of human insulin using genetically modified bacteria is a classic example of biotechnology, where bacteria are engineered to produce insulin. 5. **Statement E**: Developing a DNA vaccine. - This statement is related to biotechnology. DNA vaccines involve the use of genetic material to elicit an immune response, which is a biotechnological approach. 6. **Statement F**: Correction of a defective gene. - This statement is related to biotechnology. Gene therapy, which involves correcting defective genes, is a significant application of biotechnology. Now, let's summarize the findings: - Statements A, D, E, and F are related to biotechnology. - Statements B and C are not related to biotechnology. **Final Count**: 4 statements are related to biotechnology.
