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. Click to see full answer. More Information

Helical viruses Virtually all studies of structure and assembly of viral filaments have been made on plant and bacterial viruses. Structures have been determined using fiber diffraction methods at high enough resolution to construct reliable molecular models or several of the rigid plant tobamoviruses (related to t … 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

1) Helical capsids: The first and best example studied is the plant tobacco mosaic virus (TMV), which contains a single-stranded RNA genome and a protein coat made up of a single 17.5 kd protein. This protein is arranged in a helix around the viral RNA, with 3 nucleotides of RNA fitting into a groove in each subunit. More Information

The cylindrical helical virus type is associated with the tobacco mosaic virus. Envelope viruses, such as influenza and HIV come covered in a protective lipid envelope. Most animal viruses are classified as icosahedral and are nearly spherical in shape. The viruses within these categories share similar characteristics. More Information

Overview Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight infection and disease. HIV is a sexually transmitted infection (STI). More Information
