RNA-dependent RNA replication is a special process reserved exclusively for RNA viruses but not cellular RNAs. Almost all RNA viruses (except retroviruses) undergo RNA-dependent RNA replication by a virus-encoded RNA-dependent RNA polymerase (RdRP), which specifically replicates the viral RNA genome.
Correspondingly, is RNA used in replication?
Replication of the Viral RNA. RNA replication is associated with the nuclear membrane. Cyclization of the RNA is required for replication. Sequences from the 5′ and 3′ regions of dengue virus RNA that form a number of stem-loop structures and that also cyclize the RNA are illustrated in Fig.
In this regard, what are the steps of RNA replication?
RNA Transcription Process: The RNA transcription process occurs in three stages: initiation, chain elongation, and termination. The first stage occurs when the RNA Polymerase-Promoter Complex binds to the promoter gene in the DNA. This also allows for the finding of the start sequence for the RNA polymerase.
DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand.
