WebMar 1, 2024 · In eukaryotes, DNA replication occurs in the nucleus. There are many different origins of replication because DNA primase lays down primers at many different spots and because the DNA is much longer than in prokaryotes this helps optimize the time spent during replication. WebDNA primase forms an RNA primer, and DNA polymerase extends the DNA strand from the RNA primer. DNA synthesis occurs only in the 5' to 3' direction. On the leading strand, DNA synthesis occurs continuously. On the lagging strand, DNA synthesis restarts many …
