Techniques in DNA Analysis Descriptions A. Gel Electrophoresis 1. Separates DNA fragments based on size B. Ethidium Bromide 2. Stains DNA for visualization under UV light C. Elution 3. Cuts DNA into fragments D. Restriction Enzyme 4. Extracts DNA fragments from agarose gel

Options

  1. AA - 1, B - 3, C - 2, D - 4
  2. BA - 3, B - 2, C - 1, D - 4
  3. CA - 2, B - 1, C - 4, D - 3
  4. DA - 1, B - 2, C - 4, D - 3

Correct answer

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

Step-by-step solution

Gel electrophoresis separates DNA fragments based on size, ethidium bromide stains DNA for visualization under UV light, elution extracts DNA fragments from the agarose gel, and restriction enzymes cut DNA into fragments.
