Explain why a certain virus will attach to only one or few types of cells?
Virus attachment is dependent upon the cell surface receptor that can interact with the protein on the virus surface. The interaction is akin to a lock and a key. The key is the protein on the virus, and the lock is the cell surface receptor. A key will only get into the correct lock.
What does the protein coat in a virus do?
The capsid surrounds the genetic information of the virus (protects the genome from the environment and aids in attachment of virus to host cell). The capsid is usually inside the viral envelope (which facilitates attachment to host cell receptors), unless the virus is naked (not all viruses have viral envelopes).
What is the structure of a typical virus?
A virus is basically DNA or RNA (single- or double-stranded)surrounded by a protein capsule. Typically the protein coat, or capsid, of an individual virus particle, or virion, is composed of multiple copies of one or several types of protein subunits, or capsomeres. Some viruses contain enzymes, and some have an outer membranous envelope. Many viruses have striking geometrically regular shapes, with helical structure as in tobacco mosaic virus, polyhedral (often icosahedral) symmetry as in herpes virus, or more complex mixtures of arrangements as in large viruses, such as the pox viruses and the larger bacterial viruses, or bacteriophages . Certain viruses, such as bacteriophages, have complex protein tails. The inner viral genetic material -the nucleic acid- may be double stranded, with two complementary strands, or single stranded; it may be deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). The nucleic acid specifies information for the synthesis of from a few to as many as 50 different proteins, depending on the type of virus.
Cells belong to an organism in which kingdom?
Organism in all of the kindoms are made up of one or more cells. Only virus don't have cells, and they are not officially in one of the kingdoms.
Protein attached to only one side of the plasma membrane?
Plasma membrane is made up of proteins and phospholipids. Integral protein are attached fully on the membarne region. whereas the periphera protein bind on the surface (one side or top) of the membrane.
Why will a certain virus attach to only one or a few cell types?
Virus attachment is dependent upon the cell surface receptor that can interact with the protein on the virus surface. The interaction is akin to a lock and a key. The key is the protein on the virus, and the lock is the cell surface receptor. A key will only get into the correct lock.

Does a virus' coat contain protein?
If a virus has one, yes, and it's often referred to as a "protein coat."

Is a virus made of more than one cell?
NO! Virus are made of single unit either they are not called as cell because viruses are not consider as living beings they only contain a protein coat and a gentic material in that some time they also have capsule aroung the protein coat.
Does and element only contain on kind of protein?
An element contains no protiens. An element is made of only one type of atom. Protiens are made up of elements.
Where are computer virus made?
a computer virus can be made by any one who has read a book and has a computer. there are no special requirements to manufacture a virus.

What one of these is an infectious protein?
They are called Prion. This is the definition I fount at wordnetweb.princeton.edu/perl/webwn: "an infectious protein particle similar to a virus but lacking nucleic acid; thought to be the agent responsible for scrapie and other degenerative diseases of the nervous system".
