Question

Match List I with List II

Choose the correct answer from the options given below:

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

Hint:

- copia = LTR autonomous - Alu = Non-LTR non-autonomous - I factor = Non-LTR autonomous - Dasheng = LTR non-autonomous

Answer 1

The Correct Option is B

Concept: Retrotransposons are classified based on:
• Presence of LTR (Long Terminal Repeats)
• Ability to transpose independently (autonomous vs non-autonomous)

Step 1: Identify examples.

• copia → LTR, autonomous → A-III
• I factor → Non-LTR, autonomous → B-IV
• Dasheng → LTR, non-autonomous → C-I
• Alu → Non-LTR, non-autonomous → D-II

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

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