Codes:
| List I | List II |
|---|---|
| a) Visualization of DNA in gel electrophoresis | i) Chitinase |
| b) Precipitation of DNA | ii) Lysozyme |
| c) Breaking of cell wall of bacteria | iii) Chilled ethanol |
| d) Breaking of cell wall of fungus | iv) Ethidium bromide |
- Correct answerAa - iv, b - iii, c - ii, d – i
- Ba - iii, b - iv, c - i, d – ii
- Ca - iv, b - i, c - ii, d – iii
- Da - iii, b - ii, c - iv, d – i
Solution
Visualization of DNA in gel electrophoresis requires staining with ethidium bromide followed by exposure to UV radiation.
Precipitation of purified DNA is achieved by adding chilled ethanol.
The bacterial cell wall is broken down by the enzyme lysozyme to release DNA and other macromolecules.
The fungal cell wall, which is made of chitin, is broken down by the enzyme chitinase.
Therefore, the correct matching is a - iv, b - iii, c - ii, d - i.
Answer: a - iv, b - iii, c - ii, d – i
