Replicase

replicase

(Science: enzyme) generic (and rather unhelpful) term for an enzyme that duplicates a polynucleotide sequence (either rNA or dNA). The term is more usefully restricted to the enzyme involved in the replication of certain viral RNA molecules.

Re: Lifecycle F+RNA phages

... translated into proteins that replicate the phage RNA and direct the synthesis of any capsid proteins required to form new phage particles. The replicase enzyme makes copies of both plus and minus strands, though the latter are only used as a template to make more (+) strand for both translation ...

The Fiber Disease

... proteins of >8.7 kDa. High amino acid sequence similarity was demonstrated between a potential 33.3-kDa protein product of ORF1 of BFDV and the replicase-associated protein of porcine circovirus (PCV), subterranean clover stunt virus, and faba bean necrotic yellows virus. However, significant ...

WHY RNA IS MORE REACTIVE?

RNA has a replicase activity, that was found in some lower organism. Also, it has got self splicing ability. it can give rise to DNA using reverse transcriptase and also the polymorphic forms of RNA that are required for protein ...

I guess NOT

... I and III do the job of DNA replication. A bacteriophage exploits this host bacterium machinery to get its DNA replicated. But the human DNA replicase wont be able to replicate the phage replicon.
