RNA virus. Definition. noun. A virus containing RNA as its genetic material.The RNA may be single stranded or double stranded. Examples of RNA viruses include Reoviruses, Picornaviruses, Togaviruses, Orthomyxoviruses, Rhabdoviruses, etc.Supplement.NA virus. Definition. noun. A virus containing RNA as its genetic material.
RNA interference (RNAi) is a cellular mechanism activated by double-stranded RNA (dsRNA). Cellular dsRNA-specific RNaseIII enzymes (Dicer) recognize dsRNA and process it into double-stranded small interfering RNAs (ds-siRNAs) of 21â25 nucleotides (nt).ew biotechnology-derived crop traits have been developed utilizing the natural process of RNA interference (RNAi). However, plant-produced double stranded RNAs (dsRNAs) are not known to present a hazard to mammals because numerous biological barriers limit uptake and potential for activity.
