What is double stranded rna virus
What is double stranded rna virus-By atomic absorption analysis, we determined that the reovirus outer capsid protein sigma 3, which binds doublestranded RNA (dsRNA), is a zinc metalloprotein Using Northwestern blots and a novel zinc blotting technique, we localized the zinc and dsRNAbinding activities of sigma 3 to distinct V8 proteasegenerated fragments Zincbinding activity was contained within an aminoDouble stranded RNA what type of reovirus is found in virtually all animals?
DsRNA is a double stranded RNA, ie the RNA which is having two strands This phenomenon is seen in viruses only The doublestranded (ds)RNA viruses represent a diverse group of viruses that varySerotype 3 (T3) reoviruses induce substantially more type 1 interferon (IFNI) secretion than serotype 1 (T1) strains However, the mechanisms underlying differences in IFNI production between T1 and T3 reoviruses remain undefined Here, we found that differences in IFNI production between T1 and T3 reoviruses correlate with activation of interferon regulatory factorコンプリート! double stranded rna is found in reovirus Double stranded rna is found in reovirus a genome comprised of 10 doublestranded RNA segments encased in two concentric protein capsids Like virtually all RNA viruses, an RNAdependent RNA polymeraseRotavirus is a doublestranded RNA virus, highly contagious and resistant to several disinfectants, and is
