Question

RNA primer at the 5’ ends of Okazaki fragments in prokaryotes are removed by:

• A. Ribonuclease Z
• B. S1 nuclease
• C. P1 nuclease
• D. DNA pol I

Hint:

DNA polymerase I removes RNA primers in prokaryotic DNA replication and fills in the gaps.

Answer 1

The Correct Option is D

Step 1: Understanding the Removal of RNA Primer 
In prokaryotic DNA replication, RNA primers are removed by DNA polymerase I, which has exonuclease activity. 
Step 2: Conclusion 
DNA polymerase I is responsible for removing RNA primers from Okazaki fragments.
