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

Concept: Molecular biology processes are based on central dogma where DNA replication, transcription and translation are carried out by specific enzymes and structures.

Step 1: Identify function of ribosome.
Ribosome is the site of protein synthesis where mRNA is translated into amino acid sequence, hence it performs translation.

Step 2: Identify histone function.
Histones are basic proteins around which DNA is wrapped forming nucleosomes, which are structural units of chromatin.

Step 3: Identify DNA polymerase function.
DNA polymerase is responsible for DNA replication during cell division.

Step 4: Identify RNA polymerase function.
RNA polymerase synthesizes RNA from DNA template during transcription. \[ P-(iii),\ Q-(iv),\ R-(i),\ S-(ii) \]
