Prions do not contain DNA or RNA. They are misfolded proteins that can induce normal proteins to misfold as well, leading to the formation of aggregates that can damage cells and tissues.
No, prions aren't organisms or even organism imitators like viruses. Prions are misfolded proteins that can aggregate and cause serious neurological problems. See link below for more info about prions from Answers.com.
Viroids are small infectious agents composed of a single-stranded circular RNA that infect plants, causing diseases by disrupting normal cellular functions. Prions, on the other hand, are misfolded proteins that can induce normal proteins to misfold as well, leading to a variety of neurodegenerative diseases in animals, including humans. Both viroids and prions lack genetic material like DNA and rely on host cells for replication.
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.
No, DNA is not found in any prions. Prions are just protein - they don't contain a nucleic acid.

None of those. Prions are infectious protein molecules which do not contain DNA or RNA.

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.
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.
Yes, lysosomes do contain RNA. Some lysosomal enzymes and proteins are coded for by specific RNA molecules that are synthesized in the cell's nucleus and then transported to the lysosomes where they are translated into functional proteins.
Paramyxoviruses contain single-stranded RNA as their genetic material.
Yes, some viruses do not have DNA or RNA. Instead, they have genetic material in the form of RNA that is directly translated into proteins. Additionally, there are other biological entities, like prions, that do not contain DNA or RNA but are still able to replicate and cause disease.
Some viruses contain RNA; these are known as retroviruses. Others contain DNA.
