What else can I help you with?
Do prions only contain RNA?
yes
Do prions contain DNA or RNA?
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
What pathogen is a packet of proteins with no RNA or DNA?
A prion is a pathogen that consists solely of proteins and lacks both RNA and DNA. Prions are known to cause degenerative neurological diseases in animals and humans by inducing normal proteins to misfold and aggregate, leading to cellular damage.
What are viroids and prions?
I have no idea so go ask someone else. The similarities between viroids and prions are that both are acellular pathogens, and do not grow and they differ in the sense that prions do not have nucleic acids while viroids have the nucleic acid,RNA.
How do viroids and prions compare with viruses?
Viroids are small infectious agents consisting of a short, single-stranded RNA molecule, while prions are misfolded proteins without nucleic acid. In contrast, viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat. Viroids and prions lack the ability to replicate independently, unlike viruses which require a host cell for replication.

Would the concept that all infectious agents contain either DNA or RNA be considered a scientific fact theory hypothesis or model?
None of those. Prions are infectious protein molecules which do not contain DNA or RNA.
How are prion and viroid alike?
Prions and viroids are both infectious agents that lack typical genetic material like DNA or RNA. Prions are composed of misfolded proteins that can cause other proteins to misfold, leading to diseases like Creutzfeldt-Jakob disease. Viroids are small, circular RNA molecules that can replicate themselves within host cells and cause diseases in plants.
What basic structure do viruses share?
Unlike prions and viroids, viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Viroids do not have a protein coat and prions contain no RNA or DNA. In short, just say that all viruses have a protein coat and either DNA or RNA.
What is the differences between viriods and prions?
A prion or proteinacious infections particle is simply a protein. They exist as normal proteins in our brain termed PrP, however in certain ecepalopathy diseases these prions are thought to alter shape to a more resistant tertiary protein structure (more beta pleated sheets than alpha helices) and are termed PrPsc. It is theorised the PrPsc are able to convert normal prions to pathogenic ones. Mode of transmission between organisms is unknown as the blood brain barrier should prevent them from getting to the brain of the infected organism. A viriod however is a naked strand of DNA/RNA that causes disease mainly in plants. It does this by cell infection, and then expression of its own genetic code, hijacking the cellular protein synthesis apparatus of the cell to copy itself.
Is DNA found in all prions?
No, DNA is not found in any prions. Prions are just protein - they don't contain a nucleic acid.
Why are prions unlike any other infectious disease?
Prions are unlike other infectious diseases because they lack nucleic acid (DNA or RNA) and consist solely of misfolded proteins that can induce other proteins to misfold in a similar manner. This unique ability to self-propagate and spread within the body without the need for genetic material makes prions particularly challenging to detect and treat. Additionally, prion diseases are generally untreatable and inevitably fatal.
A prion is a viruslike particle that contains only?
A prion is actually a type of protein that can fold into an abnormal shape and cause other proteins to misfold in a similar manner. Prions are known for their ability to induce progressive and fatal neurodegenerative diseases in animals and humans. Unlike viruses, prions lack genetic material such as DNA or RNA.
