What actions do viruses have on living cells?

Answer 1

Generally, viruses infiltrate and infect healthy cells in your body, either corrupting them or destroying them completely (ie. HIV, AIDS, etc.). Though viruses like the flu can be easily cured by consuming high amounts of Vitamin C and getting lots of rest. Interesting fact, once your body recovers from a virus, it will never be infected by the same virus again, as it as naturally developed an immunity for it. You may catch some other sort of virus, or a similar type of virus (like different types of flue), though it will never be the same. Isn't the human body amazing?

Answer 2

Viruses attach to a cell and send a disease throught the body by killing off the cells or infecting them. Well that's what they do in simple terms.

____________________________________

viruses infiltrate a cell, then use the cell to reproduce, which damages or comletely desroys the cell. then more viruses come out of the cell an ifiltrate more cells, so the viruses spread through the body.

this is also true because my science teacher said so

Answer 3

They replace the cells' DNA with their genetic material (DNA or RNA) to instruct the cells to stop their usual activities and begin to create new virus particles instead. The only way viruses can replicate ("reproduce") is to take over the cells of a living host to do their bidding.

Answer 4

Viruses replicate, and they depend on cells for energy and materials in order for replication to occur.

The Oxford Concise Medical Dictionary (2010) defines a virus as a "minute particle that is capable of replication but only within living cells."

An article titled "Are Viruses Alive?" in Scientific American (Dec. 2004) discusses what viruses do to "host cells," and why they need them in terms of biochemical actions.

A section from the National Science Foundation website describes the actions as such: "Viruses enter other organisms' cells and take over their machinery, making copies of themselves, but they can't "reproduce" on their own."

Answer 5

A virus has glycoprotein antigen molecules on its surface that bind to surface protein and/or glycoprotein molecules on the cell. Once the virus has thereby attached itself to the surface of the cell it injects its nucleic acid molecule into the cell, which then takes over the cell forcing it to make millions of copies of the virus. When the cell fills with virus particles it bursts and dies.

Answer 6

They stress your cell by co-opting it's machinery and prevents it from working properly. This can sometimes result in death. Animal viruses do not kill cells directly like bacteria-phages do.

Answer 7

Viruses basically attach to a cell, implant off spring, which eat inside to out for nutrients killing the cell, then go to reproduce themselves killing multiple cells. They're like parasites.

Answer 8

It acts as a parasite (:
