As mentioned above, Pol I's primary and essential function is to excise the RNA primers from newly synthesized Okazaki fragments with its 5' → 3' exonuclease function and replace them with DNA using its polymerase function. This yields a double-stranded DNA (dsDNA) with a single strand nick between successive Okazaki fragments, a nick that is eventually sealed through the action of DNA ligase.
