Question

Match Column-I with Column-II and choose the correct option:

• A. a-i, b-ii, c-iii, d-iv
• B. a-ii, b-v, c-i, d-iii
• C. a-v, b-iv, c-ii, d-i
• D. a-v, b-i, c-iv, d-ii

Hint:

Remember:
Biolistics $\rightarrow$ Plants.
Micro-injection $\rightarrow$ Animals.
Lysozyme $\rightarrow$ Bacteria.
Cellulase $\rightarrow$ Plants.
Chitinase $\rightarrow$ Fungi.

Answer 1

The Correct Option is C

To solve the question, we need to match items from Column-I with their relevant associations in Column-II:

1. Biolistic gun - Plant cell (v): The biolistic gun, also known as a gene gun, is commonly used to deliver DNA into plant cells. This method involves shooting microscopic particles coated with DNA into plant tissues.
2. Chitinase - Fungal cell (iv): Chitinase is an enzyme that breaks down chitin, a major component of the fungal cell wall. Thus, it is related to fungal cells.
3. Ti - Tumor inducing (ii): Ti refers to the Ti plasmid from the bacterium Agrobacterium tumefaciens, which is known for its role in transferring genes to plant cells, causing tumors.
4. Ca⁺⁺ - Bacterial cell (i): Calcium ions (Ca⁺⁺) are used in bacterial transformation to facilitate the uptake of genetic material, linking them to bacterial cells.

Based on the explanations above, the correct matching is:

• a-v: Biolistic gun - Plant cell
• b-iv: Chitinase - Fungal cell
• c-ii: Ti - Tumor inducing
• d-i: Ca⁺⁺ - Bacterial cell

Therefore, the correct answer is: a-v, b-iv, c-ii, d-i.
