Prions are an infectious particle made of protein. They do not contain DNA or RNA.
The pathogen composed only of protein is known as a prion. Prions are infectious agents that cause neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, particularly in the brain. Unlike viruses and bacteria, prions do not contain nucleic acids (DNA or RNA) and are resistant to conventional methods of sterilization. Examples of diseases caused by prions include Creutzfeldt-Jakob disease and mad cow disease (BSE).
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.
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.
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.

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.
Several entities do not contain DNA, including certain viruses, which may have RNA instead of DNA as their genetic material. Additionally, non-living things such as rocks, water, and minerals do not possess DNA, as they are not biological entities. Furthermore, structures like prions, which are misfolded proteins, do not contain DNA or RNA.
Organisms that have no genetic material at all are typically classified as acellular entities, such as viruses. While viruses contain genetic material (either DNA or RNA), they lack the cellular structure and machinery necessary for independent life. However, in the context of strictly no genetic material, certain prions—misfolded proteins that can induce abnormal folding of normal proteins—are considered to have no genetic material. Prions are infectious agents but 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.
