Matching Scientists with Biological Discoveries
This section provides a clear matching of scientists from List-I with their significant discoveries in List-II, focusing on key contributions in genetics and molecular biology.
Key Scientists and Discoveries Explained
| List-I Scientist | List-II Discovery | Details |
|---|---|---|
| A. Yule | II. Multiple factor hypothesis | G. Udny Yule proposed the concept that traits can be influenced by multiple genetic factors (polygenic inheritance). |
| B. Watson & Crick | III. Double helical structure of DNA | James Watson and Francis Crick determined and published the double helix model of DNA structure in 1953. |
| C. Jacob & Monod | IV. Operon concept | François Jacob and Jacques Monod described the operon model, explaining gene regulation in prokaryotes. |
| D. Fleming | I. Mitosis | Walther Flemming extensively studied cell division and described the process of mitosis and chromosome behavior. |
Deriving the Correct Matching
Based on the established scientific contributions:
- A. Yule corresponds to II. Multiple factor hypothesis.
- B. Watson & Crick correspond to III. Double helical structure of DNA.
- C. Jacob & Monod correspond to IV. Operon concept.
- D. Fleming corresponds to I. Mitosis.
Therefore, the correct sequence is A-II, B-III, C-IV, D-I.
