It's like a shield and a cover. The protein shell protects the DNA codes inside the virus from being exposed to the immune system, and when the virus attacks, the protein shell opens up, and injects a string of DNA codes into the infected cell. If there were not protein coats to protect viruses then it will literally die in seconds after entering the host's system.
The virus tries to match the recognition glycoprotein on the outside of the cell it is trying to invade, for docking purposes, or for entry purposes. Generally the membrane that covers this type of virus was taken from a cell it lysed on exit.

Why is protein synthesis important for cells and viruses?
Protein synthesis is important for viruses because the virus forces the host cell to make proteins that the cell does not need, but the virus does to repoduce. Protein synthesis is important for cells because the proteins are essential for all cellular activites.
Do virus help in digestion?
Bacteria aide in digestion, not viruses.
How does virus checker help us?
It scans your computer for viruses
How do capsomeres help in viruses?
Answer by Techsupportcapsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.
Are viruses alive?
ARE VIRUSES EVEN ALIVE? We're starting with the smallest of the small here. Some scientists argue that viruses are not even living things. We suppose it's easier to give you a list of what they can't do as opposed to what they can. What viruses can't do:(1) They can't reproduce on their own. They need to infect or invade a host cell. That host cell will do all the work to duplicate the virus.(2) They don't respond to anything. You can poke them or set up barriers, it doesn't matter. They either function or they are destroyed.(3) They don't really have any working parts. While there some advanced viruses that seem fancy, viruses don't have any of the parts you would normally think of when you think of a cell. They have no nuclei, mitochondria, or ribosomes. Some viruses do not even have cytoplasm.We've already established what viruses aren't. Let's talk about what they are. Every virus has a few basic parts. The most important part is a small piece of DNA or RNA(never both). That strand of nucleic acid is considered the core of the virus. The second big part is a protein coat to protect the nucleic acid. That coat is called thecapsid. The capsid protects the core but also helps the virus infect new cells. Some viruses have another coat or shell called the envelope. The envelope is made of lipids and proteins in the way a regular cell membrane is structured. The envelope can help a virus get into systems unnoticed and help them invade new host cells.so u decide..!
What has been developed to help fight viruses?
antibiotics help bacterial infections that could cause a virus other wise they give you can get a shot of a small amount of that virus to help build an immunity to that virus.
Does carbohydrates help virus or hurt virus?
Normaly neither. A virus is an infectious agent that needs a living cell to make more viruses. Otherwise, a virus just floats around. Some viruses do need carbohydrates to be made, but without a cell a carbohyrate is useless. To some extent, though, certain carbohydrates help a virus by powering the cell that builds viruses. Putting it simply, a lone carbohydrate will most likely do nothing to a lone virus.
How can I get rid of the virus on my computer?
There are many anti-virus programs available. Many of the free programs will do a decent job of removing viruses. Other viruses may require professional help in removal.
How can vaccine help the natural defence against VIRUS?

What makes virus nonliving?
1. The virus cannot reproduce on its own, it needs to have a host cell to help it reproduce. 2. The virus is not even a single-celled organism! 3. The virus can't even function on its own! The virus needs to have a host cell to live! 4. The virus does not grow on the inside of the protein coat. 5. The virus only has two main parts: the DNA and the protein coat, which protects the DNA.

What are the 3 types of micro organisms?
The three main types of microbes are fungi, bacteria and viruses. Bacteria are usually smaller than fungi and virus is the smallest type of microbe.
