Hepatitis B virus is made up of only one protein called the core protein, which forms the viral capsid.
What else can I help you with?
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.
A virus is made of DNA and?
A virus is a tiny bundle of genetic material - either DNA or RNA - carried in a shell called a viral coat, or capsid, which is made up of protein. Some viruses have an additional layer around this coat called an envelope. When a virus particle enters a cell and begins to reproduce itself, this is called a viral infection. The virus is usually very, very small compared to the size of a living cell. The information carried in the virus's DNA allows it to take over the operation of the cell, converting it to a factory to make more copies of itself. For example, the polio virus can make over one million copies of itself inside a single, infected human intestinal cell.
What is Organism that carries out only one life process reproduction?
A virus is an organism that only carries out one life activity. This activity is known as reproduction. The study of viruses is called virology.
Why will a certain virus will attach to only one or a 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.

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.
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.
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.

How come meat is good for you?
Protein is good for you. Meat is an excellent source of protein, but not the only one.
which only one enzyme is non protein in nature?
Pepsin) whereas other enzymes are composed of both protein part and non-protein part. The complete enzyme molecule (with both protein part and non-protein part) is known as holo-enzyme. The protein part is known as Apo-enzyme Non- protein part may be co-factor or co-enzyme
Does dichlorodiphenyltrichloroethane stand for a type of virus?
No, it is a chemical formula for the insecticide known as DDT. A virus is a twist of RNA or DNA inside a protein sheath, it doesn't have a chemical formula as such, not one that could be easily written.
