What base is found in DNA but not in RNA? What does RNA primase do in DNA replication? What are the base pairing rules for RNA? What are adenine, guanine, cytosine and thymine? Which base is found only in RNA? In a DNA molecule, which of the following does cytosine pair with? a....
What does RNA primase do in DNA replication? Why is DNA polymerase a required part of PCR? a. It synthesizes proteins. b. It synthesizes new DNA. c. It separates RNA from DNA. d. It degrades the template DNA. Is transfer RNA a protein?

Primer RNA In subject area: Neuroscience Primer RNA refers to RNA molecules that are used to initiate DNA synthesis during the process of replication. They are synthesized by an enzyme called primase and are necessary because DNA polymerase cannot initiate the synthesis of polynucleotides. AI ...
Replicative DNA polymerases cannot initiate DNA synthesis de novo and rely on dedicated RNA polymerases, primases, to generate a short primer. This primer is then extended by the DNA polymerase. In diverse archaeal species, the primase has long been know
Effect of 4-quinolones and novobiocin on calf thymus DNA polymerase alpha primase complex, topoisomerases I and II, and growth of mammalian lymphoblasts. The influence of ciprofloxacin, nalidixic acid, norfloxacin, novobiocin, and ofloxacin on elements of eucaryotic DNA replication was investigated in...
