i don't know in detail, but they have a DNA strand (RNA) like the ones in our cells which tell them to attack certain cells. but their DNA can very easily change or mutate, causing it to attack other cells. if our body has fought a certain virus with a certain DNA, then the next time a virus with the same DNA strand comes, our body will remember it and destroy it quickly. but some viruses, like the flu causing virus, change their DNA just a tiny bit, but it's enough for our body to not recognize it, therefore taking longer to register and destroy.

Where does the virus multiply?
Viruses replicate inside the host cells they infect. They hijack the cellular machinery of the host to make copies of themselves, leading to the multiplication of the virus.
How does a hidden virus multiply?
A hidden virus multiplies by hijacking the host cell's machinery to replicate its genetic material and produce new viral particles. The virus then releases these new particles, which can go on to infect other cells and continue the replication cycle.
How does the structure of a virus help it survive?
The structure of a virus, with its protein coat and genetic material, allows it to enter host cells, replicate its genetic material, and produce new virus particles. This structure also helps protect the virus from the host's immune system and other environmental factors. Additionally, the compact size and shape of viruses enable them to efficiently infect host cells and spread from one organism to another.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
How are virus cultured?
Viruses can be cultured in tissue or cell media.
Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
The human immunodeficiency virus may infect what cells?
sperm cells
How many different kinds of cells can any given virus infect?
A given virus can infect a limited range of cell types, often specific to certain hosts or tissues. This specificity is largely determined by the virus's surface proteins, which must match receptors on the host cell's membrane. For example, some viruses may infect only certain types of animal cells, while others may target specific plant or bacterial cells. Overall, the diversity of cells a virus can infect varies widely between different viruses.
How do you describe the reproduction of polio in the body?
Polio virus can infect only human being. Like other viruses, polio virus infect the cells. After getting attached to the cell, the virus genome is inserted into the cell body. The genetic material of the host is broken into small fragments and assembled as per the genome of the polio virus. Multiple such copies are formed and then released in the body to infect the new cells.
What is a host cell for a virus?
A host cell for a virus is a cell that the virus can infect and hijack to replicate itself. The virus enters the host cell, takes over its machinery to produce more virus particles, and then spreads to infect other cells.
Can a virus infect any type of cell?
Yes.It infects fungi,plants,animals and bacterias
Do viruses replicate in cells of organisms?
Yes. This is the reason that viruses infect cells. The virus injects its genetic material, either DNA or RNA, which then takes over the cell's activities and turns the cell into a virus factory, causing the cell to make new virus parts and assemble them. Eventually the cell ruptures and the new viruses are free to infect other cells.
Do viruses attack healthy cells?
because they want to make more of their kind
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.
HIV initially infects cells of the nervous system.?
HIV, the human immuno-deficiency virus, does not infect nerve cells, it infects white blood cells. (false)
What is lytic reproduction?
ex. a virus enters a cell, replicates, and then "lyses" (ruptures) the cell. those virus particles are now free to infect other cells.
Where does the virus multiply?
Viruses replicate inside the host cells they infect. They hijack the cellular machinery of the host to make copies of themselves, leading to the multiplication of the virus.
