a cell wall
Correct. For APEX it is, A protective shell around a virus.
caspsid
Viruses are not cells and are not made of cells: they are small entities that reproduce inside of cells.Viruses have many different shapes and forms. They tend to resemble spirals, spheres, and various types of three-dimensional polygons.The internal structure of a virus is a strand of RNA surrounded by a protein shell.
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.
A virion is an entire virus particle. It is the complete form of a virus with an outer protein shell, an inner core of DNA or RNA, and a capsid.
protein shell
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.
Made of protein and called a capsid.
Made of protein and called a capsid.
a typical virus has a core of DNA or RNA and a protein coat
Correct. For APEX it is, A protective shell around a virus.
caspsid
The protein coat or shell of a virus particle, surrounding the nucleic acid or nucleoprotein core
it is composed of individual morphological units called capsomers.
A helical virus has a spiraling structure similar to a spiral staircase. The virus genome is arranged in the middle of the spiral staircase. The Tobacco mosaic virus is a helical 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."
It's like a shield and a cover. The protein shell protects the DNA codes inside the virus from being exposed to the immune system, and when the virus attacks, the protein shell opens up, and injects a string of DNA codes into the infected cell. If there were not protein coats to protect viruses then it will literally die in seconds after entering the host's system. The virus tries to match the recognition glycoprotein on the outside of the cell it is trying to invade, for docking purposes, or for entry purposes. Generally the membrane that covers this type of virus was taken from a cell it lysed on exit.
