Webb12 mars 2024 · TMV (Tobacco Mosaic Virus) is a rod-shaped virus. The rod has a core that contains helically coiled single-stranded RNA. There is a protective covering of protein called capsid around the infective part. The capsid consists of small subunits called capsomeres and has antigenic property. 9. Viruses have: (a) DNA enclosed in a protein … WebbThey were initially grouped by shared morphology. 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 double-stranded. More recently, molecular analysis of viral replicative cycles has further refined their classification. Figure 1.

WebbDouble stranded RNA replicates in a semiconservative manner similar to DNA to produce two double-stranded progeny molecules. Single-stranded genetic RNA found in some viruses, such as, TMV is called the plus (+) strand RNA; it acts as a template for the synthesis of a complementary minus (-) strand to yield a double-stranded RNA molecule.
