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 else can I help you with?
What of the following pathogens is one of the exceptions to the rule of typical cell structure?
One of the exceptions to the typical cell structure is the virus. Unlike bacteria and eukaryotic cells, viruses lack a cellular structure, consisting only of genetic material (DNA or RNA) surrounded by a protein coat. They cannot carry out metabolic processes independently and require a host cell to replicate. This unique structure distinguishes them from other pathogens that have more conventional cell structures.
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 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 of the pathogens is one of the exceptions to the rule of typical cell structure?
One notable exception to the typical cell structure is the virus, which is not classified as a living organism because it lacks cellular structure. Viruses consist of genetic material (either DNA or RNA) encased in a protein coat, and they require a host cell to replicate and carry out life processes. Unlike bacteria and other cellular pathogens, viruses do not possess the machinery for metabolism or reproduction on their own, which sets them apart in the realm of pathogens.
Which if the following Pathogens is one exception to the rule of typical cell structure?
One exception to the typical cell structure is the virus, which lacks cellular components such as a cell membrane and organelles. Instead, viruses consist of genetic material (either DNA or RNA) encased in a protein coat, and they require a host cell to replicate and carry out metabolic processes. This makes them fundamentally different from bacteria, fungi, and other cellular organisms.
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
