What is the helical virus?
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
What is the general shape of viruses?
A virus can have one of two structures. These are: •Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. •Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
Are viruses classified by their shape?
A virus can have one of two structures. These are: •Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. •Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
Is the T2 phage virus polyhedral or helical?
polyhedral
What is structure viruses?
A virus has a protein coat called a capsid with either DNA or RNA inside. A virus can have one of three structures. These are: 1. Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. 2. Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses. 3. Polyhedral Cylindrical shapes: Tobacco mosaic virus Wheat streak virus Hepatitis C
Is the TMV virus isosahedral virus?
Yes, the Tobacco mosaic virus (TMV) is indeed an icosahedral virus. It is a rod-shaped virus composed of helical protein subunits, which are arranged in a spiral that forms an icosahedral structure.
What are the 4 basic virus shapes?
Spacecraft, spherical, crystal, and cylinder , and these are the 4 basic shapes of virus
What shapes do virus assume?
Viruses can have various shapes, including helical, icosahedral, complex, or enveloped. These shapes are determined by the way the viral proteins and genetic material are arranged within the virus particle.
Do Compare and contrast helical and icosahedral viral shapes and diseases?
Helical viruses have a rod-like shape with a helical symmetry, such as the tobacco mosaic virus, while icosahedral viruses have a polyhedral shape made up of 20 equilateral triangular faces, like adenoviruses. Diseases caused by helical viruses include Ebola and influenza, while diseases caused by icosahedral viruses include the common cold and polio.
What is frank dance s helical model of communication?
what is the use of dance helical communication? helical communicqationis the communication of helical
What three main structures do viruses have?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA.Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.The naked viruses are more resistant to changes in the environment.A virus can have one of three structures. These are:Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus.Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.Polyhedral virus.
What is Helical Sequence?
