Proteins,carbohydrates,nucleic acid and some have Lipids.Virus are also made up of those as other animals.
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.
Some naked viruses include poliomyelitis, warts, the common cold, chickenpox, shingles, mononucleosis, herpes simplex (cold sores), influenza, herpes viruses and HIV (AIDS).
Some enveloped viruses include norovirus (stomach bug), rotavirus and human papillomavirus (HPV).
The envelope can be damaged by freezing temperatures, chlorine, and phenol. If damaged the virus cannot infect.
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
They are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently.
What else can I help you with?
What are the viruses the infect bacteria called?
Bacteriophages are viruses that infect bacteria.
How do you infect others computers with viruses?
YOU don't infect other computers with viruses.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
What does Caulimoviridae infect?
Caulimoviridea are retro viruses that infect plants.
What do viruses that cause physical diseases infect?
It depends on what kind of virus. Viruses can infect any cell in the human body. Viruses such as HIV infect the immune system; air-born viruses, such as H1N1 or a cold, infect the respiratory system; neurological viruses, like rabies infect the brain (the virus is usually carried to it by peripheral nerves); and viruses like polio effect the nervous system, which can create paralysis.
Why could a virus not infect another virus?
Viruses only infect living organisms and since they are not alive, they can not infect other viruses. The question is interesting though.
What did the first viruses do?
Infect cells.
Do viruses only infect only animals?
No, they dont, they can infect plants and bacteria too.
Can a Mac virus infect a PC?
There are no mac viruses and if there were, no
When viruses infect bacteria what is it called?
A bacteriophage
Can myspace really infect computers with viruses?
yes but its not the site its the people who put viruses on the site
What are viruses that infect bacteria called?
the virus that infects bacteria is bacteriophage
