The correct Answer is:
To analyze the statements provided in the question regarding biotechnology, we will evaluate each statement one by one. ### Step-by-Step Solution: 1. **Statement A: Large scale production involves the use of bioreactors.** - **Explanation:** Large scale production of biological products, such as enzymes, antibiotics, or vaccines, is typically conducted in bioreactors (also known as fermenters). These vessels provide controlled environments for the growth of microorganisms or cells, allowing for optimal production conditions such as temperature, pH, and nutrient supply. - **Conclusion:** This statement is correct. 2. **Statement B: Genetic engineering involves the use of restriction endonuclease, DNA ligase, appropriate plasmid or viral vectors.** - **Explanation:** Genetic engineering techniques utilize restriction endonucleases to cut DNA at specific sequences, allowing for the insertion of desired genes. DNA ligase is then used to join the DNA fragments together. Plasmids or viral vectors serve as carriers to introduce the modified DNA into host cells. - **Conclusion:** This statement is also correct. 3. **Statement C: Modern biotechnology uses genetically modified organisms.** - **Explanation:** Modern biotechnology heavily relies on genetically modified organisms (GMOs) for various applications, including agriculture, medicine, and research. GMOs are organisms whose genetic material has been altered using genetic engineering techniques to exhibit desired traits. - **Conclusion:** This statement is correct. 4. **Statement D: Bacterial cell wall is digested by lysozyme.** - **Explanation:** Lysozyme is an enzyme that breaks down the peptidoglycan layer of bacterial cell walls, leading to cell lysis. This property is utilized in various applications, including the isolation of bacterial DNA and the study of bacterial cells. - **Conclusion:** This statement is correct. ### Final Conclusion: All four statements (A, B, C, and D) are correct regarding their relevance to biotechnology.

    Read the following and answer questions from Q.1. to Q.5. given below: Plants having foreign genes in their genome through genetic engineering are called transgenic plants. Genes can be incorporated either through a vector or through direct introduction of DNA. Bt cotton is a genetically modified organism which is pestresistant. It contains gene cry I Ac and cry II Ab of Bacillus thuringiensis. It is used to control lepidopterans, coleopterans and dipterans. Bt cotton can resist cotton bollworm and produce higher yields. Cry gene produces cry protein or Bt toxin. It is an endotoxin which remains as protoxin in plants and converted to active toxin after getting ingested by the insects. Alkaline pH of the insect gut solubilizes the protein crystals, the activated toxin creates pores to the mid guts wall of theinsects which cause them to death. What is true about Bt cotton crops?
