After a region of DNA has been replicated,________ removes the RNA primers.
A)DNA polymerase I
B)DNA polymerase III
C)DNA helicase
D)RNA primase
E)DNA ligase

Question

Quizplus · Accepted Answer

DNA polymerase I is responsible for removing RNA primers during DNA replication. It has a 5' to 3' exonuclease activity that allows it to remove the RNA primers and replace them with DNA nucleotides. DNA polymerase III is the main polymerase responsible for DNA synthesis, while DNA helicase unwinds the double helix and RNA primase synthesizes the RNA primers. DNA ligase seals the gaps between the Okazaki fragments, which are created during discontinuous DNA synthesis on the lagging strand.
