Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
What did the first viruses do?
Infect cells.
Are viruses always larger than cells they infect?
no
What are most viruses highly specific to the cells they infect?
somehow
Are viruses general or highly specific to the cells they can infect?
Highly specific
Where would viruses most likely grow?
Viruses can only live in living organisms (viruses themselves are not actually living). They might infect cells in our body, such as throat cells (infection of throat cells causes sore throat).
What cells are infected by the human immunodeficiency virus considering that most viruses infect a specific kind of cell?
T-cells.
Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
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.
how are new viruses produced How might this process cause harm to the infected cell?
All viruses kill they cells that they infect. If not right away then later.
How does the common cold spread in the human body?
The Lytic Cycle describes the process. This is the mechanism by which viruses infect a host, take over the function of the cells, and use them to replicate millions of new viruses in your body. The word lytic is used since the infected host cells are lysed (split open), and killed in the process, as the new virus particles mature and are ready for release in the body. Common cold viruses infect the cells of the mucous tissue in humans, mostly that of the respiratory system. However, cold viruses also infect the tissues in the eyes, mouth and the rest of the gastrointestinal system with mucous tissue.
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
