primase (Science: enzyme) The enzyme that polymerises nucleotide triphosphates to form oligoribonucleotides in a 5′ to 3′ direction. The enzyme synthesises the rNA for RNA dNA sequences that later become okazaki fragments and also rNA primers for some types of phage using an sDNA template.

There is a wide list of phytochemicals which act as inhibitors and a few of them are glycosylated flavones suppressing topoisomerase IV activity (Bernard et al., 1997), myricetin inhibiting DnaB helicase (Griep et al., 2007), allicin inhibiting RNA synthesis (Feldberg et al., 1988) and compounds from the plant Polygonum cuspidatum inhibiting bacterial DNA primase (Hegde et al., 2004).
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.
DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase.Primase catalyzes the synthesis of a short RNA (or DNA in some organisms) segment called a primer complementary to a ssDNA (single-stranded DNA) template. After this elongation, the RNA piece is removed by a 5' to 3' exonuclease and refilled with DNA.
RNA Primase and the RNA Primer Wouldn't it be nice if we had another helper to solve this problem? Well, fortunately, we do, and it's yet another enzyme.It's called RNA primase.The job of RNA primase is to make, or synthesize, a primer for replication to start.
primase: ( prī'māz ), A polymerase that acts on a template DNA strand to produce RNA, resulting in the formation of an RNA primer needed in RNA replication. Synonym(s): dnaG [ prim er + -ase]

One would think that all patients receiving conventional chemotherapy and radiation might benefit from treatment with these RNA primers.However, since they are not patentable drugs (as they are natural products) and the amount of money required to go through the procedures of the Food and Drug Administration (FDA) for them to become approved as a drug is astronomical for a small supplement ...
