Webb25 nov. 2024 · Circular RNAs (circRNAs) are a recently discovered class of noncoding RNAs found in many species across the eukaryotic kingdom. These intriguing RNA species are formed through a unique mechanism that is known as back splicing in which the 5′ and 3′ termini are covalently joined. WebbThe reason why TMV contains a single-stranded RNA instead of double-stranded RNA or DNA is due to its mode of replication. TMV replicates by using the host cell's translation machinery to produce new virus particles. The RNA genome of TMV serves as a template for the production of viral proteins, which then assemble to form new virus particles. maniac\u0027s brentwoodWebbPDF On Sep 1, 1964, W SHIPP and others published Double-stranded RNA from tobacco leaves infected with TMV Find, read and cite all the research you need on ResearchGate koreatown clinics
