Choose the correct answer from the options given below:
| Column I | Column II | ||
|---|---|---|---|
| A | Frederick Griffith | I | Genetic code |
| B | Francois Jacob & Jacque Monod | II | Semi-conservative mode of DNA replication |
| C | Har Gobind Khorana | III | Transformation |
| D | Meselson & Stahl | IV | Lac operon |
Correct answer · Option 4
A-III, B-IV, C-I, D-II
Explanation
Frederick Griffith discovered bacterial transformation (A-III). Jacob and Monod proposed the Lac operon model (B-IV). Har Gobind Khorana contributed to deciphering the genetic code (C-I). Meselson and Stahl proved the semi-conservative mode of DNA replication (D-II). Therefore, the correct match is A-III, B-IV, C-I, D-II.
