A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. In living organisms, primers are short strands of RNA. A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur.
The RNA primer is a short strand of RNA that initiates DNA replication. So, the primer that initiates DNA replication isn't even made out of DNA! Don't get confused about the difference between the RNA primer and the RNA primase. Again, the enzyme that puts together the RNA primer is called RNA primase. Just remember that the one with -ase is the one that's the enzyme.
