\includegraphics[width=0.6\linewidth]{png}
Choose the correct answer from the options given below:

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

Hint:

To quickly solve this historical match:
- Robert Brown \(\rightarrow\) Nucleus (B - I).
- Friedrich Miescher \(\rightarrow\) Nucleic acid Nuclein (D - III).
Using these two well-known historical facts will help you find the correct option easily.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Cell biology involves the study of cellular organelles and biomolecules.
This question tests historical knowledge regarding the discovery and naming of these key cellular components.

Step 2: Detailed Explanation:
Let us match each cellular structure or molecule with its discoverer:
- A. Endoplasmic reticulum: While Keith Porter and Albert Claude detailed its structure in 1945 using electron microscopy, the French cytologist Charles Garnier first identified and described these filamentous structures in the cytoplasm in 1897, calling them "ergastoplasm" (later identified as the endoplasmic reticulum).
Thus, A matches with IV.
- B. Nucleus: The cell nucleus was discovered and described by the Scottish botanist Robert Brown in 1831 during his study of orchid cells.
Thus, B matches with I.
- C. Centrosomes: The centrosome was discovered by Edouard Van Beneden in 1883, but it was described and named by Theodor Boveri in 1888, who detailed its role in organizing cell division.
Thus, C matches with II.
- D. Nucleic acid: Nucleic acids (originally named "nuclein") were first isolated from the nuclei of white blood cells by the Swiss physician Friedrich Miescher in 18
Thus, D matches with III.
The correct matching sequence is: A-IV, B-I, C-II, D-III.

Step 3: Final Answer:
The correct option is (D).
