The document summarizes the process of DNA replication. First, helicase splits the DNA strands apart and single-stranded binding proteins prevent the strands from rejoining. On the leading strand, primase provides a starting point for polymerase III to replicate continuously. On the lagging strand, RNA primase creates RNA primers and polymerase III synthesizes fragments called Okazaki fragments. Polymerase I then replaces the RNA with DNA and ligase joins the fragments, creating two new DNA double helices.

3. First the helicase comes to split the DNA strand apart.


4. Then the helicase starts to split the strand and the single
Stranded binding proteins join to keep the strands from coming
back together.

5. Leading Strand

Lagging Strand

6. After the strand is split the primase gives the leading strand a starting point.


7. Then the polymerase III comes along to replicate.

10. However, while the leading strand replicates the lagging strand is also replicating. Fi
RNA primase creates RNA primers which gives polymerase III a starting point

13. Polymerase III begins to replicate and the segments of DNA are called okasaki fragment


14. After replication is done within the space Polymerase I turns the RNA into DNA


15. The ligase then comes and creates phosphodiester bonds between the fragments of DN

18. Two new strands of DNA are created as the process is completed!
