Q: Which enzyme removes RNA primer?
ANS:
- DNA polymerase I (Pol I) is responsible for removing RNA primers during DNA replication.
- It has both polymerase and exonuclease activities.
- It is involved in DNA replication and repair processes.
| Enzyme | Description |
| DNA Polymerase | Enzyme |
| Function | Catalyzes the synthesis of DNA molecules by adding nucleotides to the growing DNA strand |
| Types | DNA Polymerase I, DNA Polymerase II, DNA Polymerase III (prokaryotes), DNA Polymerase alpha, delta, epsilon (eukaryotes) |
| Substrate | Deoxyribonucleotide triphosphates (dNTPs) |
| Primer | Required for the initiation of DNA synthesis on the template strand |
| Template Strand | Provides the sequence information for the synthesis of a complementary DNA strand |
| Proofreading | DNA polymerases have proofreading activity to correct errors in DNA replication |
| Exonuclease Activity | DNA polymerases have 3′ to 5′ exonuclease activity to remove incorrectly incorporated nucleotides |
| Replication Role | Synthesizes both the leading and lagging strands during DNA replication |
| Processivity | The ability of DNA polymerase to remain attached to the template strand and continue synthesis without dissociating |
| Additional Functions | Involved in DNA repair, recombination, and other DNA metabolic processes |
