Mad cow disease is a prion prions are known for causing a number of degenerative brain diseases in various animals Viroids ONLY exist in plants and cause errors in regulatory systems that control plant growth. They always exist withing host cells. Therefore there is no example in humans

What is a infectious agent composed of a simple strand of RNA with no protein component?
A infectious agent composed of a simple strand of RNA with no protein component is called a viroid. Viroids are smaller and simpler than viruses, consisting only of a short, circular RNA molecule. They can infect plants and disrupt their normal growth processes.
Which of these is an infectious agent composed of both nucleic acids and protein?
A virus is an infectious agent composed of both nucleic acids (either DNA or RNA) and protein.
Does the viroid prion virus or the vector cause mad cow disease?
Mad cow disease, also known as bovine spongiform encephalopathy (BSE), is caused by prions. Prions are abnormal proteins that can cause normal proteins in the brain to become misshapen, leading to neurodegeneration. The disease can be spread through contaminated meat consumption.
What is viriod?
A viroid is a small, circular RNA molecule that infects plants and can cause diseases. Unlike viruses, viroids do not have a protein coat and rely on the host plant's cellular machinery for replication. They can disrupt the normal functioning of plants and impair their growth and development.
Does a virus have a protein coat?
Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.
What is the name of the viriod responsible for cucumo virus?
The viroid responsible for cucumber pale fruit viroid (CPFV) infection in cucumbers is called the cucumber pale fruit viroid (CPFV). This viroid can cause symptoms such as yellowing, stunting, and distortion of leaves in infected plants.
Is SARS a prion or viroid?
SARS (Severe Acute Respiratory Syndrome) is caused by a virus, specifically a coronavirus. It is not caused by a prion or a viroid.
Does a viroid have RNA?
yes . viroids have RNA but in naked condition.
What is a non-cellular infectious agent?
A virus, a viroid or a prion
Which of these is an infectious agent composed of a simple strand of RNA with no protein component?
Viroid
What do you call a virus that infects plants?
A virus that infects plants is called is viroid.
A disease causing particle made of RNA without a capsid is called?
A Prion. It transmits a mis-folded protein state, and replicates by causing the host's proteins to replicate into its mis-folded pattern. Mad Cow disease is an example of a prion.
If virus is the smallest creature than what is VIROID?
Viroids are infectious, circular RNA molecules that are even smaller than viruses. They lack a protein coat and rely on host cell machinery for replication. Viroids can cause disease in plants, interfering with their normal growth and development.
What is the differet between virus and virod?
Virus is a small infectious agent that replicates only inside the living cells of other organisms Virus can infect all type of life form such as animal ,plant and microorganism ,bacteria and archaea Viroid are a smallest infectious pathogens known but larger only prions Viroid can infect mostly plant pathogens
What has the author T O Diener written?
T. O. Diener has written: 'Viroids and viroid diseases' -- subject(s): Viroid diseases of plants, Viroids
What is a infectious agent composed of a simple strand of RNA with no protein component?
A infectious agent composed of a simple strand of RNA with no protein component is called a viroid. Viroids are smaller and simpler than viruses, consisting only of a short, circular RNA molecule. They can infect plants and disrupt their normal growth processes.
How virus prion and viroid evolve?
Prions are misfolded proteins and may form because of some misreading of the DNA code. Virions are extracellular state of a virus with nucleocapsid.
