The spherical virus particles ( virions) of Matonaviridae have a diameter of 50 to 70 nm and are covered by a lipid membrane ( viral envelope ), derived from the host cell membrane. There are prominent "spikes" (projections) of 6 nm composed of the viral envelope proteins E1 and E2 embedded in the membrane.Which is RNA virus has the highest GC content?
The genome has the highest G+C content of any currently known single stranded RNA virus (~70%). Despite this high GC content its codon use is similar to that of its human host.Where are homologous sequences found in The Togavirus?
There are three sites that are highly conserved in togaviruses: a stem-and-loop structure at the 5' end of the genome, a 51-nucleotide conserved sequence near the 5' end of the genome and a 20-nucleotide conserved sequence at the subgenomic RNA start site. Homologous sequences are present in the rubella genome.How is the RUV virus transmitted between humans?
RuV is transmitted via respiration between humans. On the basis of differences in the sequence of the E1 protein, two genotypes have been described which differ by 8 - 10%. These have been subdivided into 13 recognised genotypes - 1a, 1B, 1C, 1D, 1E, 1F, 1G, 1h, 1i, 1j, 2A, 2B and 2C.
