Going down because of the new technology is this age
<span>Primase is the enzyme that synthesizes small fragments of RNA in the strand lagging in DNA replication. The primase does not need a primer to synthesize and the RNA residues are removed by DNA polymerase I, due to their exonuclease capacity and filled with DNA fragments also by DNA Pol I. Finally, all these discontinuous DNA segments are linked by a ligase.</span>
