What is a virus called outside a host cell?
A virus outside a host cell is generally referred to as a virion. This is the inactive form of the virus that is unable to replicate until it enters a suitable host cell.
What destroys virus particles outside the host?
capsid wall
What is extracellular virus?
An extracellular virus is a virus that exists outside of host cells, in the external environment. It is typically in a metabolically inactive state and is composed of genetic material (either DNA or RNA) encased in a protein coat, sometimes surrounded by a lipid envelope. Extracellular viruses are responsible for infecting host cells, where they can replicate and propagate their genetic material. Their ability to survive outside host cells allows them to spread and infect new hosts.
How long can mumps virus survive outside a host?
few seconds
Can aids virus survive under outside temperature?
No. HIV needs a host. It does not live long, outside the body.
How long a hepatitis virus can stay outside the host?
Hep B can live for up to a week outside the body.
Why would it not be advantageous for a virus to kill its host?
It would not be advantageous for a virus to kill its host because if the host dies, the virus would also die since it needs the host to replicate and spread. It is more beneficial for a virus to keep the host alive so it can continue to infect other individuals.
Can a virus live outside a cell?
No
What covers the outside of a virus and is it called?
The outside of a virus is covered by a protein coat known as a capsid. In some viruses, this capsid is further surrounded by a lipid envelope, which is derived from the host cell membrane. The capsid and envelope serve to protect the viral genetic material and facilitate the virus's entry into host cells.
Why is the cell invaded by the virus called a host cell?
The cell invaded by the virus is called a host cell because it provides the environment and resources necessary for the virus to replicate and multiply. The virus uses the host cell's machinery to produce more viruses, ultimately leading to the destruction of the host cell.
Does a virus get energy by reacting chemicals with oxygen?
No, a virus has no metabolism whatsoever. It relies entirely on tricking the host cell to do its work; while outside a cell, the virus doesn't move, eat, or anything.
Can the HIV virus live outside the human body in fluids if not smeared?
Yes, infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate or breast milk.
