Match the Column I with Column II :
| Column I | Column II |
| A. Isolation of DNA fragments | 1.Virus infecting bacteria |
| B. Amplification of gene | 2.Natural polymer from sea weeds |
| C. Agarose | 3. Gel electrophoresis |
| D. Bacteriophages | 4. PCR |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2)- A-3,B-4,C-2,D-1
| Column I | Column II |
| A. Isolation of DNA fragments | 3. Gel electrophoresis |
| B. Amplification of gene | 4. PCR (Polymerase Chain Reaction) |
| C. Agarose | 2. Natural polymer from seaweeds |
| D. Bacteriophages | 1. Virus infecting bacteria |
Explanation:
- Isolation of DNA fragments involves separating and purifying specific DNA fragments using techniques like gel electrophoresis.
- Amplification of genes is achieved through the Polymerase Chain Reaction (PCR), a method to produce multiple copies of a specific DNA segment.
- Agarose is a natural polymer extracted from seaweeds and is commonly used as a matrix in gel electrophoresis to separate DNA fragments.
- Bacteriophages are viruses that infect bacteria and can be used as vectors to transfer foreign DNA into bacterial cells during genetic engineering experiments.
