Helicase is a protein that breaks the hydrogen bonds between the 2 strands. SSbps is a single-strand binding protein that helps keep the strands from unraveling. Then later on primase, on the other side of the replication bubble is synthesized in fragments, so primase comes in the DNA polymerase which comes to an Okazaki fragment where a new protein comes in called RNAse H which removes the primer, and DNA polymerase pulls in the correct material. Then DNA ligase connects the two ends together.
