Match the Column I with Column II :

A-3,B-4,C-2,D-1

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 sea weeds

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 sea weeds 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.
