DNA replication involves many different steps. By number,

arrange the following four steps in order from start to finish: DNA polymerase [POL-uh-muh-rays] synthesizes a new DNA strand, DNA ligase [LY-gays] repairs nicks in the

phosphodiester [fos-foh-dy-ES-tuhr] backbone, replication bubble opens at origin, primase builds the primer.
