What is a major difference between DNA polymerase I and DNA polymerase II？

Question

Accepted Answer

∻Answer∻ ⚹ The major difference between DNA polymerase I and DNA polymerase III is their primary functions and associated activities in DNA replication. ⚹ ∻Solution∻ ‖ a ⋮ Primary function: DNA polymerase I is primarily involved in the removal of RNA primers from the DNA and replacing them with the appropriate nucleotides, whereas DNA polymerase III is the main enzyme responsible for DNA synthesis during replication. ‖ ‖ b ⋮ Associated activities: DNA polymerase I has exonuclease activity in both the 5' to 3' and 3' to 5' directions, which allows it to remove primers and fill in the gaps with DNA. DNA polymerase III, on the other hand, has high processivity and 3' to 5' exonuclease activity for proofreading but lacks 5' to 3' exonuclease activity. ‖ ∻Key Concept∻ ⚹ Functional distinction in DNA replication ⚹ ∻Explanation∻ ⚹ DNA polymerase I is involved in primer removal and gap filling, while DNA polymerase III is the primary enzyme for strand elongation and proofreading during DNA replication. ⚹◊What are the primary functions of DNA polymerase I and DNA polymerase II enzymes in DNA replication?⍭ Generate me a similar question◊
