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 provides this 3' end to allow nucleotides to be added. A promoter is a region on the DNA that allows RNA Polymerase (enzyme that builds the RNA molecule from the DNA template strand) to attach to the DNA. The RNA Polymerase makes the RNA strand that eventually becomes the mRNA used in protein synthesis. So, Primer used in DNA synthesis; Promoter used in RNA synthesis.
