What does virus host range mean?
Virus host range refers to the range of organisms or cell types that a particular virus can infect. Some viruses have a broad host range and can infect multiple species, while others have a narrow host range and can only infect specific hosts. The host range is determined by factors such as the virus's ability to enter host cells and replicate within them.
What do enveloped viruses possess?
As the virus is leaving the cell (budding), it sometimes takes along a part of the cell's membrane called the envelope. Those viruses without an envelope are called "naked" viruses. Those with one are said to be enveloped.
Are prokaryote eukaryote virus multicellular unicellular or both?
Virus particles are not cells or life forms, they are just some nucleic acids coated with proteins and few functional enzymes to infect its host and establish the production of new particles. In absence of host they are unable to do this.
What is the coating around a virus's core made of?
THe outer shell of a virus is called the capsid, and consists of various proteins, which are arranged to enable the virus to enter and control a host cell. These proteins are called protomers and are assembled in units called capsomeres.
What is a virus surrounded by?
The nucleic acid of a virus is covered by a protein capsid.
What does virus host range mean?
Virus host range refers to the range of organisms or cell types that a particular virus can infect. Some viruses have a broad host range and can infect multiple species, while others have a narrow host range and can only infect specific hosts. The host range is determined by factors such as the virus's ability to enter host cells and replicate within them.
What is the outer layer of the virus that helps it enter its host?
The outer layer of a virus is called the capsid. Some viruses have an envelope over the capsid either one help the virus enter its' host.
Cell in which a virus reproduces?
A virus reproduces inside a host cell. It takes over the host cell's machinery to replicate its own genetic material and produce new virus particles. This can cause harm to the host cell and lead to the spread of the virus to other cells.
Where must viruses be found if they are to reproduce?
A virus "replicates" [the term often heard in place of "reproduces"] inside a host cell with the process called the Lytic Cycle. The details of the steps of the Lytic Cycle are in the related questions below in the Related Questions section.Basically, once the virus has found a suitable host that is made up of the type of host cells that its virus type uses (i.e., plant, animal ~ including insects to humans, or bacteria), it attaches to the host. Then the virus implants the "key" to its genetic makeup into the cell. When this DNA "key" (or RNA in some viruses) of the virus is inserted into cells of a host, it allows the cells to be hijacked and, at the appropriate time for that particular virus, it instructs the host to make more virus particles. The virus can either lie dormant, such as in some cases of the HIV/AIDS virus, or immediately become active and command the host cell to start the replication processes.If the virus becomes active, it can then turn the host cell into a 'factory' for making more viruses. The result usually, but not always, is that the host becomes ill because the cells are no longer functioning as they should for the host while working on the job of the replication. With each cycle of replication, the virus particles can invade even more and more cells until the host's immune system (or other defense) can catch up to kill the invader.How_do_viruses_reproduce

Which does not refer to the shape of a virus?
A bacillus does not refer to the shape of a virus. The capsid of a virus is what determines the shape of a virus.
What are some characteristics of viruses?
some characteristics of a virus: - needs a host - can contain DNA or RNA - can have an envelope cell - is an acellular organism
What is most important for attachment of a virus to a host cell?
While we are constantly referring to bi-lateral specificity, as in the functions of Dna, here is a case where a virus offers out it's 'hand': it seems likely that it expects to reach for, find and attach to some outstretched Cell Membrane Component.
What does neuraminidase do for a virus?
Neuraminidase is an enzyme found on the surface of some viruses, such as the influenza virus. Its main function is to cleave sialic acid residues from host cells, which helps the virus to release from infected cells and spread to other cells in the body. Inhibiting neuraminidase activity can prevent viral replication and spread.
What do enveloped viruses possess?
As the virus is leaving the cell (budding), it sometimes takes along a part of the cell's membrane called the envelope. Those viruses without an envelope are called "naked" viruses. Those with one are said to be enveloped.
Do viruses have membrane bound organeles?
No, a virus rarely has more than some strands of DNA stored in the capsule. The virus injects the DNA into the host cell for the cell to construct copies of the virus.
Are prokaryote eukaryote virus multicellular unicellular or both?
Virus particles are not cells or life forms, they are just some nucleic acids coated with proteins and few functional enzymes to infect its host and establish the production of new particles. In absence of host they are unable to do this.
