Helical Virus Function
Helical viruses - PubMed
Virions of filamentous viruses have numerous mechanical functions, including cell entry, viral disassembly, viral assembly, and cell exit. The plant viruses, which infect multicellular organisms, also use virions or virion-like assemblies for transport within the host. More Information

Helical Viruses. Helical capsids are made up of a single type of protein subunit stacked around a central axis to form a helical structure. The helix may have a hollow center, which makes it look like a hollow tube. This arrangement results in rod-shaped or filamentous virions. More Information
What is a helical virus? - AskingLot.com
A helical virus is a virus that has a capsid shaped in a filamentous or rod-shaped structure that has a central cavity that encloses its nucleic acid. An icosahedral virus is a virus consisting of identical subunits that make up equilateral triangles that are in turn arranged in a symmetrical fashion. More Information

Most animal viruses also have an envelope surrounding a polyhedral or helical nucleocapsid that is typically derived from host cell membranes by a budding process and are called enveloped viruses. Specific proteins or glycoproteins on the viral surface are used to attach viruses to the surface of its host cell. More Information

Viruses are grouped on the basis of size and shape, chemical composition and structure of the genome, and mode of replication. Helical morphology is seen in nucleocapsids of many filamentous and pleomorphic viruses. Helical nucleocapsids consist of a helical array of capsid proteins (protomers) wrapped around a helical filament of nucleic acid. More Information

helix with the RNAor DNAprotected within. Tobacco mosaic virus(TMV) is a classic example of the helical nucleocapsid. In TMV the protein subunits form broken disklike structures, like lock washers, which form the helical shell of a long rodlike virus when stacked together (Figure 6-11a). More Information

Structure of Viruses | Boundless Microbiology
Each virus is a nucleic acid (RNA or DNA) surrounded by a coating, referred to as an envelope or capsid. Viruses encode capsid proteins which encase the nucleic acid. Sometimes, viral proteins combine with host proteins to make the envelope. The shape of a viral coat has implications on how a virus infects a host. More Information
