How Do The Double Stranded Rna Viruses Replicate Their Genomes Quora
Later, groups of viruses were classified by the type of nucleic acid they contained, DNA or RNA, and whether their nucleic acid was single or doublestranded However, these earlier classification methods grouped viruses differently, because they were based on different sets of characters of the virus The most commonly used classification method today is called the(a) Rabies virus has a singlestranded RNA (ssRNA) core and an enveloped helical capsid, whereas (b) variola virus, the causative agent of smallpox, has a doublestranded DNA (dsDNA) core and a complex capsid Rabies transmission occurs when saliva from an infected mammal enters a wound The virus travels through neurons in the peripheral nervous system to the central nervous

Viruses Have Big Impacts On Ecology And Evolution As Well As Human Health The Economist
RNA interference (RNAi) is a genetic regulatory system that functions to silence the activity of specific genes RNAi occurs naturally, through the production of nuclearencoded premicroRNA (premiRNA), and can be induced experimentally, using short segments of synthetic doublestranded RNA (dsRNA) They are the negative or minusstrand RNA viruses, the closely related ambisense RNA viruses, and doublestranded RNA viruses For each of these groups of viruses, the first synthetic event after genome penetration is transcription This is accomplished by viral proteins (including the RdRp) that enter cell with the genome Keywords RNA virus, positivestrand RNA, DoubleStranded RNA Doublestranded RNA viruses usually have a polyhedral structure with the diarrhea viruses being a common example SingleStranded RNA Singlestranded RNA viruses are usually of two subtypes those that can serve as messenger RNA (mRNA) and those that serve as a template for mRNA Examples include Ebola viruses,
I will keep it very very short and simple dsRNA is very critical in regulation of gene expression at translational level In our system we have specific miRNA (micro RNA) that are somewhat complementary to a specific mRNA and miRNAmRNA binding forms a double stranded molecule that is degraded by our system at a cellular levelHence, they need a living cell to replicate Also, they are infectious particles doublestranded RNA EBV Epstein–Barr virus EMCV encephalomyocarditis virus HBV hepatitis B virus HCV hepatitis C virus HDV hepatitis delta virus HPV human papillomavirus IAV influenza virus KSHV Kaposi sarcoma herpesvirus LANA1 latencyassociated nuclear antigen m1ψ N1methylpseudouridine m 6 A N 6 methyladenosine MAPK
