What else can I help you with?
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
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 is the function of the capsomere?
Capsomeres are protein subunits that make up the capsid, which is the protein coat surrounding a virus. They help in the assembly of the capsid structure and protect the genetic material of the virus. Capsomeres also aid in the attachment of the virus to host cells during infection.
What is another name for the protein coat of a virus?
We sometimes see the word capsid used to speak of the "shell" enclosing the virus. Use the link below to check facts and learn more.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
What is the host range of a virus?
protein shell
What do you call the protein shell of a virus?
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic material of the virus.
What is the outside shell of a virus is called what?
Made of protein and called a capsid.
The outside shell of a virus is called what?
Made of protein and called a capsid.
What is the structure of typical virus?
a typical virus has a core of DNA or RNA and a protein coat
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
What is a caspid'?
The protein coat or shell of a virus particle, surrounding the nucleic acid or nucleoprotein core
A viral capsid is composed of?
it is composed of individual morphological units called capsomers.
Can a smaller virus affect a bigger virus?
No because a virus is simply genetic material coated in a protein shell. Internally, viruses do not have the components, which are commonly found in cells, necessary to propagate "offspring."
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 shape of the norwalk virus?
Norovirus, often referred to as the Norwalk virus, is typically described as having a spherical shape. It measures about 27 to 40 nanometers in diameter and is classified as a non-enveloped virus. Its structure includes a single-stranded RNA genome encapsulated in a protein shell, which contributes to its stability and ability to survive in various environments.
What are some examples of helical virus?
Helical viruses are characterized by their spiral-shaped capsids. Examples include the Tobacco Mosaic Virus (TMV), which affects plants, and the Rabies virus, which infects animals and humans. Other examples include the Influenza virus and the Ebola virus, both of which can cause significant disease in humans. These viruses often have a simple structure, with their genetic material encased in a helical protein shell.
