Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Hugo de Vries = Mutation.
Flemming = Mitosis.
Stern = Crossing over proof (Cytology).
Meselson-Stahl = Semi-conservative DNA replication.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question matches prominent scientists in the field of biology and genetics with their landmark discoveries or coining of terms.

Step 2: Detailed Explanation:

• Hugo de Vries (A-III): A Dutch botanist who is famous for proposing the Mutation Theory of evolution in $1901$, based on his work with the evening primrose (Oenothera lamarckiana).

• W Flemming (B-I): Walther Flemming, a German biologist, was the first to detail the process of cell division. He coined the term "mitosis" in $1882$ from the Greek word for thread.

• C Stern (C-IV): Curt Stern provided the cytological proof of crossing over in Drosophila in $1931$, showing that genetic recombination is accompanied by an actual physical exchange of chromosome segments.

• MS Meselson and FW Stahl (D-II): Matthew Meselson and Franklin Stahl performed a classic experiment in $1958$ using $15$N isotope to prove the semi-conservative nature of DNA replication.
Final Answer:
Matching the scientific contributions gives A-III, B-I, C-IV, and D-II.
This corresponds to option (A).
