Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

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

Hint:

Crick was involved in both the structure (with Watson) and the theory of information flow (Central Dogma).
Always remember the "S-B" duo for Chromosomes (Sutton-Boveri) and the "B-T" duo for Enzymes (Beadle-Tatum).

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question matches fundamental concepts in genetics and molecular biology with the scientists who proposed them.

Step 2: Detailed Explanation:

• Central Dogma of Molecular Biology (A-III): Proposed by Francis Crick in 1957. It describes the flow of genetic information: DNA \( \rightarrow \) RNA \( \rightarrow \) Protein.

• Chromosomal Theory of Inheritance (B-IV): Proposed independently by Walter Sutton and Theodor Boveri in 1902. They identified that the behavior of chromosomes during meiosis explained Mendel's laws of inheritance.

• DNA Double Helical Structure (C-I): Solved by James Watson and Francis Crick in 1953 using X-ray diffraction data from Rosalind Franklin and Maurice Wilkins.

• One Gene-One Enzyme Hypothesis (D-II): Proposed by George Beadle and Edward Tatum in 1941 based on their work with the bread mold Neurospora crassa. (Later refined to one gene-one polypeptide).
Final Answer:
Matching: A-III, B-IV, C-I, D-II.
This corresponds to option (A).
