Question

Match List - I with List - II. Choose the correct answer from the options given below: 

List - I	List - II
P. Ribosome	(i) Replication
Q. Histone	(ii) Transcription
R. DNA polymerase	(iii) Translation
S. RNA polymerase	(iv) Nucleosome

• A. \(P-(i), Q-(ii), R-(iii), S-(iv)\)
• B. \(P-(ii), Q-(i), R-(iii), S-(iv)\)
• C. \(P-(i), Q-(ii), R-(iv), S-(iii)\)
• D. \(P-(iii), Q-(iv), R-(i), S-(ii)\)

Hint:

Ribosome = Translation, DNA polymerase = Replication, RNA polymerase = Transcription, Histone = Nucleosome formation.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question tests the fundamental roles of biological molecules in the central dogma of molecular biology, specifically protein synthesis and DNA packaging.
Step 2: Key Formula or Approach:
Analyze the biological function of each listed item:
- Ribosome: The site of protein synthesis, involved in translation.
- Histone: Basic proteins around which DNA is wrapped to form nucleosomes.
- DNA polymerase: The primary enzyme responsible for synthesizing DNA during replication.
- RNA polymerase: The enzyme that synthesizes RNA from a DNA template during transcription.
Step 3: Detailed Explanation:
- P (Ribosome) matches (iii) Translation.
- Q (Histone) matches (iv) Nucleosome.
- R (DNA polymerase) matches (i) Replication.
- S (RNA polymerase) matches (ii) Transcription.
The correct matching sequence is P-(iii), Q-(iv), R-(i), S-(ii).
Step 4: Final Answer:
The correct option is (D).
