The reason why a host cell is unable to make it`s protein while the invading virus replicates is because viruses typically not considered living organisms
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.
I'm unable to display images as I'm a text-based AI. However, the influenza virus is a spherical particle with proteins on its surface that help it infect cells. It contains genetic material in the form of RNA and is known for causing the flu in humans.
Effective vaccines usually target specific surface proteins of viruses. These surface proteins are often essential for the virus to infect host cells. By targeting these proteins, vaccines can train the immune system to recognize and fight off the virus more effectively.
H1N1 virus replicates by entering human respiratory cells, hijacking the cell's machinery to make copies of its own genetic material and proteins. These new viral components are then assembled into new viruses, which are released from the host cell to infect other cells and continue the cycle of infection.
I believe it is called the Ly-tic cycle. The virus attaches itself to a cell and injects DNA. The viral DNA enters the Lytic cycle and new viruses are made. The cell then breaks open and viruses are released. I believe AIDS is such a virus.
polymorphic
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.
A virus replicates its DNA in a cell when it infects the host
Polymorphism
virus
A polymorphic virus not only replicates itself by creating multiple files of itself, but it also changes it's digital signature every time it replicates.
virus
antigen
A virus.
A harmful program that replicates itself to other computers form yours.
Worm is a computer virus that replicates from one computer to another over a network. It does all the nonsense work as that of a computer virus.
ex. a virus enters a cell, replicates, and then "lyses" (ruptures) the cell. those virus particles are now free to infect other cells.
