During replication of RNA viruses, there are at least three types of RNA that must be synthesized: the genome, a copy of the genome (copy genome), and mRNAs. Some RNA viruses also synthesize copies of subgenomic mRNAs. RdRp is the key player for all of these processes. RdRps of all RNA viruses probably arose from a common ancestor.

RNAi Step 2: Border guards Another set of RNAs and proteins pick up some of the chopped-up viral RNA from Step 1. You can think of them as setting up security checkpoints near a cell’s ribosome, where translation occurs. These molecular border guards compare incoming messenger RNA (mRNA) that comes from either the virus or the host cell against their small pieces of the virus’s genetic code.

Specifically, viruses depend on host cells for: (1) energy, mainly in the form of nucleoside triphosphates, for polymerization involved in genome and viral protein synthesis; (2) a protein-synthesizing system for synthesis of viral proteins from viral mRNAs (some viruses also require host enzymes for posttranslational modification of their prote

Introduction RNA viruses are obligate intracellular parasites characterised by extremely high genetic variability and phenotypic diversity, facilitating infection of an extensive range of hosts [ 1, 2, 3 ].

RNA virus replication/transcription ~ ViralZone Taxonomy and replication strategies of different types of RNA viruses. An RNA virus is a virus—other than a retrovirus—that has ribonucleic acid as its genetic material. The nucleic acid is usually single-stranded RNA but it may be double-stranded (dsRNA). Notable human diseases caused by RNA viruses include the common cold, influenza, SARS, MERS, COVID-19, Dengue Virus, hepatitis C
