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.

How do you classify a virus?
Nature of the nucleic acid in the virionSymmetry of the protein shellPresence or absence of a lipid membraneDimensions of the virion and capsid
What is the difference of PROVIRUS and VIRION?
A provirus is the virus' genetic material integrated with the genetic material of the host cell. Some viruses stay in this form inside a cell until a specific stimulus causes the provirus to start to reproduce and lyse, or burst, the cell. For instance, some prophages (a provirus from a bacteriophage) the process doesn't continue until UV radiation hits the bacterium. A virion is the name of the actual virus particle. The virion is comprised of the capsid and the DNA (or RNA) of the virus. The term virion is used in a similar way that bacterium is when referring to a single bacterial cell. Some virions, such as HIV also have a phospholipid bilayer that they gain by 'budding' from the host cell. When a cell is lysed the provirus gives way to viral progeny, the virions.
What the differences between virion and virus?
Virions are physical entities contain nucleocapsid ,capsid and sometime envelop. It exist extracellularly. Viruses are genetic material that occur intracellularly.
What is a membrane envelope?
All viruses lack cell membranes but some animal viruses have a membrane similar in composition to a cytoplasmic membrane surrounding their capsids called an envelope. This is a membrane envelope. Viruses that have envelopes are called enveloped virion, without the envelope they are called a nonenveloped or naked virion. The envelope is composed of a phospholipid bilayer and proteins such as glycoproteins.
How do capsomeres help in viruses?
Answer by Techsupportcapsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.
When did Pierre Virion die?

What is the term for a virus particle that does not have a host?

How big is the Alfalfa mosaic virus?
It is rather small. The range for the length of the virion particle is about 30-57 nm. Since it is a virion , it is smaller than any virus.
What structural property of a virion has in common with cellular organism?
A virion is the infectious form of a virus outside of the cell before it invades. Both cells and viruses have genetic material.
When was Pierre Virion born?
Pierre Vannier was born on January 20, 1986, in Roubaix, Nord, Nord-Pas-de-Calais, France.
