What else can I help you with?
How does a virus affect humans?
A virus affects humans by invading a cell. The virus then forces the cell to produce viral material rather than cell material. This causes the cell to replicate the virus rather than itself.
Group of microorganisms composed only of hereditary material wrapped in a protein covering?
This description fits the definition of a virus. Viruses are not considered living organisms because they lack the ability to carry out metabolic processes on their own and reproduce by invading host cells.
What is the medical term meaning foreign body bacteria or virus?
A pathogen is a foreign body, bacteria, or virus.
The virus that causes AIDS is damaging to the body because it?
targets cells that fight invading microbes
How virus act?
Viruses act by invading host cells and hijacking the cell's machinery to replicate themselves. Once a virus attaches to a host cell, it injects its genetic material, which can be either DNA or RNA. This genetic material then directs the host cell to produce viral components, leading to new virus particles being assembled and released, often killing the host cell in the process. This cycle of infection and replication can spread the virus to other cells and hosts.
Where is the genetic material of the virus located?
The genetic material of a virus is located inside its capsid.
What cells response to an invading virus that the body has already been vaccinated against?
Antibodies
What does the cell do to the invading virus?
When a virus invades a cell, the cell recognizes the foreign invader and activates its defense mechanisms. This includes producing antiviral proteins and triggering an immune response, which may involve apoptosis (programmed cell death) to prevent the virus from replicating. Additionally, specialized immune cells may target and destroy infected cells to limit the spread of the virus. Overall, the cell employs various strategies to eliminate the virus and protect the organism.
Why is a host cell unable to make its own proteins if the invading virus replicates?
When a virus infects a host cell, it hijacks the cell's machinery to replicate its own genetic material and proteins instead of the host cell's. This often leads to disruption of the host cell's normal protein synthesis processes, which can prevent the cell from making its own proteins.
What enzyme in the human body is used to repel an invading virus?
The enzyme used to repel an invading virus in the human body is interferon. Interferons are proteins released by cells in response to viral infections, and they help to activate the immune system and inhibit viral replication.
Where is the material of a virus located?
If you mean the nuclear material, it is located in the capsid of the virus. It can be either RNA or DNA.
What is the invading material in the body which triggers the body to produce an antibody?
Pathogens
