Enzyme Function Matching Explained

This question requires matching enzymes listed in Column I with their correct biological functions from Column II. Let's analyze each enzyme:

Primase Function: DNA Dependent RNA Synthesis

• Primase synthesizes short RNA primers. These primers are essential for DNA polymerase to start synthesizing new DNA strands. Therefore, Primase performs DNA dependent RNA synthesis. This corresponds to option 4 in Column II.

Reverse Transcriptase Function: RNA Dependent DNA Synthesis

• Reverse transcriptase is an enzyme commonly found in retroviruses. It synthesizes a DNA strand using an RNA molecule as a template. This process is known as RNA dependent DNA synthesis. This corresponds to option 3 in Column II.

RNA Replicase Function: RNA Dependent RNA Synthesis

• RNA replicase (also known as RNA-dependent RNA polymerase) is an enzyme that synthesizes RNA from an RNA template. This is crucial for the replication of many RNA viruses. The function is RNA dependent RNA synthesis. This corresponds to option 1 in Column II.

DNA Polymerase III Function: DNA Dependent DNA Synthesis

• DNA Polymerase III is the primary enzyme responsible for DNA replication in prokaryotes. It synthesizes new DNA strands by adding nucleotides to a DNA template. This function is DNA dependent DNA synthesis. This corresponds to option 2 in Column II.

Summary of Enzyme-Function Pairs

Based on the analysis, the correct matches are:

• P. Primase - 4. DNA dependent RNA synthesis
• Q. Reverse transcriptase - 3. RNA dependent DNA synthesis
• R. RNA Replicase - 1. RNA dependent RNA synthesis
• S. DNA Polymerase III - 2. DNA dependent DNA synthesis

This corresponds to the matching P-4, Q-3, R-1, S-2.
