Question

Match the LIST-I with LIST-II. LIST-I: A. Yule, B. Watson & Crick, C. Jacob & Monod, D. Fleming. LIST-II: I. Mitosis, II. Multiple factor hypothesis, III. Double helical structure of DNA, IV. Operon concept.

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

Hint:

Watson and Crick are remembered for DNA double helix, while Jacob and Monod are remembered for the operon concept.

Answer 1

The Correct Option is C

Concept:
This question is based on important scientists and their discoveries or concepts in genetics and biology.

Step 1: Yule.
Yule is associated with the multiple factor hypothesis. \[ A\rightarrow II \]

Step 2: Watson and Crick.
Watson and Crick proposed the double helical structure of DNA. \[ B\rightarrow III \]

Step 3: Jacob and Monod.
Jacob and Monod proposed the operon concept. \[ C\rightarrow IV \]

Step 4: Fleming.
Fleming is associated with mitosis. \[ D\rightarrow I \] Therefore: \[ A-II,\ B-III,\ C-IV,\ D-I \] \[ \therefore \text{Correct Answer is (C)} \]
