Is adenavirus and RNA virus?
Adenovirus have an icosahedral capsid with a glycoprotein spike at each vertex and has DNA as their genome. RNA is not an virus, but a macromolecule (nucleic acid)
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.
What is the structure of a virus like?
Viruses are ranges in different sizes and structures. HIV, HBV, influenza are all spherical in shape. Phages like T phages carry an icosahedral structures. M13 phages, ebola appear as hair like (or tube) structures. TMV appears as rod like structure.
What instrument is used to observe the structure of a virus?
Electron microscope
Can you show the structure of H1N1 virus with a neat diagram?
We are not able to create diagrams for you, but if you follow the link provided in the related link section below, you will see a picture of the structure of Swine Flu, the A-H1N1/09 virus.
What is structure viruses?
A virus has a protein coat called a capsid with either DNA or RNA inside. A virus can have one of three structures. These are: 1. Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. 2. Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses. 3. Polyhedral Cylindrical shapes: Tobacco mosaic virus Wheat streak virus Hepatitis C
What is the general shape of viruses?
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.
Are viruses classified by their shape?
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.

What is andenovirus?
A non-enveloped icosahedral DNA virus commonly causing gastroenteritis. It is the second most common cause of viral gastro, second to the rotavirus.
What shape is a hepatitis a virus?
Coccus is the shape and some pictures ive seen is Staphylo Staphylo-Coccus
What is the protein coat that surrounds a virus called?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What three main structures do viruses have?
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.A virus can have one of three 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.Polyhedral virus.
What shapes do virus assume?
Viruses can be helical and icosahedral forms or even more complex structures. Most viruses are about one one-hundredth the size of the average bacterium.
What type of shape is a virus?
There are 4 types of viruses with different shapes. Tobacco Mosaic Virus - Rod-shaped due to its helical capsid. Adenoviruses - Icosahedral capsid with glycoprotein spikes edging out at each vertex. Influenza Viruses - Spherical. Outer envelope studded with glycoprotein spikes. Bacteriophage T4 - Consists of an icosahedral head, a long tail sheath and small tail fibers (leg-like appearance).
