Question

Match List - I with List - II.

Choose the most appropriate match from the options given below:

• A. A-III, B-I, C-IV, D-II
• B. A-I, B-II, C-IV, D-III
• C. A-III, B-I, C-II, D-IV
• D. A-IV, B-I, C-II, D-III

Hint:

- Euchromatin = Active DNA - Heterochromatin = Inactive, tightly packed DNA - RNase = RNA-destroying enzyme - Some viruses (like poliovirus) have RNA genome

Answer 1

The Correct Option is A

Concept: These terms relate to chromatin structure and RNA biology.

Step 1: Match each term.

• Euchromatin → Loosely packed, transcriptionally active → A-III
• Heterochromatin → Densely packed DNA → B-I
• RNA → Genetic material of some viruses (e.g., Poliovirus) → C-IV
• RNase → Enzyme that causes RNA degradation → D-II

Step 2: Write correct matching.
\[ A\text{-III},\quad B\text{-I},\quad C\text{-IV},\quad D\text{-II} \]

Step 3: Final conclusion.
Thus, the correct option is: \[ (A) \]
