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 can have one of two structures. These are:
•Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus.
•Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
A typical virus consists of genetic material (either DNA or RNA) surrounded by a protein coat called a capsid. Some viruses also have an additional lipid envelope derived from the host cell membrane.
they all have a protein coat and an inner core that protects the genetic material

What is the helical virus?
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
What is a typical virus made of?
A typical virus is made up of a core of genetic material, either RNA or DNA. It is engulfed by a protective coat referred to as a capsid which is made up of protein.
What substance is the coating of a virus made of?
The coating of a virus is made of protein molecules. These proteins can vary in composition and structure, helping the virus to attach to host cells and invade them.
What is the typical structure of the object shown?
Without the "object" it is impossible to answer this question.
What instrument is used to observe the structure of a virus?
An electron microscope is used to observe the structure of a virus. This powerful microscope is capable of providing detailed images of viruses at a nanometer scale due to its high magnification capabilities.
What is the structure of typical virus?
a typical virus has a core of DNA or RNA and a protein coat
How much does a typical virus weigh in femtograms?
A typical virus can weigh anywhere from a few femtograms to a few nanograms, depending on the type and size of the virus. On average, a typical virus weighs around 10-1,000 femtograms.
Which description of a virus is correct?
A virus has no cell structure, but it has genes :)
A typical virus has a core composed of?
DNA or RNA
What is the structure of a typical Moneran?
single celled cylindrical structure
What is power mosfetdraw internal structure of a typical power mosfet device?
draw interstructure of a typical powerMOSFET device (semiconductor structure)
Three movements is a typical formal structure for what baroque?
Three movements is a typical formal structure for a baroque Concerto Grosso.
What is the helical virus?
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
What is a typical virus made of?
A typical virus is made up of a core of genetic material, either RNA or DNA. It is engulfed by a protective coat referred to as a capsid which is made up of protein.
How many bars does a typical blues structure have?
A typical blues structure has twelve bars. however they can have 8 or sometimes 16 but usually 12.

The disease that come from a virus.
Icosahedron refers to the structure of a virus's?
capsid
