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.
SUMMARY: 1.DNA polymerase synthesizes DNA while RNA polymerase synthesizes RNA. 2.In contrast with the DNA polymerase, RNA polymerases do not necessarily require the so called primer to start the process and they actually have no proofreading systems. nucleotide can be added to DNA polymerase only on a pre-existing 3â-OH group which requires a primer so that it may add to the nucleotide. The so called primers do contain DNA and RNA base. DNA has the base thymine while RNA has uracil as its base.
