What are prions?

How do they cause diseases?
Can They reproduce?

Answers:
A prion (IPA: ['prin][1] listen (help·info)) — short for proteinaceous infectious tiny part — (by analogy to virion) is a type of infectious agent. It is made only of protein. All infectious protein particle found so far are believed to infect and propagate by refolding abnormally into a structure which is competent to convert normal molecules of the protein into the noticeably structured form. These prions are generally slightly resistant to denaturation by protease, heat, radiation, and formalin treatments[2], although potency or infectivity can be reduced. The occupancy does not, however, a priori preclude other mechanisms of nouns.

Prion has also come to refer to the specific protein (or gene) associated near and generally believed to be responsible for transmissible spongiform encephalopathies (TSEs), the first identified infectious protein. These include scrapie (a disease of sheep), chronic wasting disease, (in deer and elk), deviation Creutzfeldt-Jakob disease (vCJD), and bovine spongiform encephalopathy (BSE or mad cow disease), adjectives caused by homologous proteins contained by different species.[3] It should be noted that the same gene is responsible for spongiform encephalopathies which are not specified to be transmissible, as well as some non-neurological diseases. Some require a mutation for nouns to occur, and nearby are respective mutations which can prevent transmission for most of the TSEs. A non-disease function of the prion gene is not agreed, but an area of considerable live research.

All of these diseases affect the structure of the brain or other neural tissue, and all are vicious and untreatable. However, a vaccine has be developed in mice that may provide insight into providing a vaccine surrounded by humans to resist prion infections. (see external links below, Science Daily article on vaccine).

Proteins showing prion behaviour are also found surrounded by some fungi. Some fungal prions may not be associated with any disease; it is unknown whether these prions represent an evolutionary dominance for their hosts. All known prions are believed to infect and propagate by formation of an amyloid fold, surrounded by which the protein polymerizes into a fiber with a core consisting of tightly stuffed beta sheets. Other mechanisms may exist surrounded by yet undiscovered infectious protein particle.

A prion is a rogue protein. I do not know if they reproduce but they are implicated in wasting diseases resembling mad cow, or scrapie. They hold been passed on through surgical instruments even after sterilization.

Protein Fragments responsible for Mad Cow disease. It is theorize they can send bio-information subsidise to DNA, which is opposite the ordinary flow of genetic information from DNA, via mRNA, to proteins.

They are free radicals that could do cancers or diseases within your body.

Prions do replicate themselves. They are like a virus but much worse. There is no opening to kill prions.

prions are stray particle of proteins which cause irritation to the cell as they enter the cell and replicate. they cause copious diseases mainly "batty cow" disease which affects cattle. they actually come from normal cell and get virulent due to not working dna reading.

A prion — short for proteinaceous infectious particle — (by analogy to virion) is a type of infectious agent. It is made lone of protein. All infectious protein particles found so far are believed to infect and propagate by refolding curiously into a structure which is able to convert conventional molecules of the protein into the abnormally structured form. These prions are largely quite resistant to denaturation by protease, warmness, radiation, and formalin treatments, although potency or infectivity can be reduced.

Prion has also come to refer to the specific protein (or gene) associated next to and generally believed to be responsible for transmissible spongiform encephalopathies (TSEs), the first identified infectious protein. These include scrapie (a disease of sheep), chronic wasting disease, (in deer and elk), change Creutzfeldt-Jakob disease (vCJD), and bovine spongiform encephalopathy (BSE or mad cow disease), adjectives caused by homologous proteins contained by different species.

All of these diseases affect the structure of the brain or other neural tissue, and all are deadly and untreatable. However, a vaccine has be developed in mice that may provide insight into providing a vaccine within humans to resist prion infections.

Proteins showing prion behaviour are also found contained by some fungi. Some fungal prions may not be associated with any disease; it is unknown whether these prions represent an evolutionary help for their hosts. All known prions are believed to infect and propagate by formation of an amyloid fold, contained by which the protein polymerizes into a fiber with a core consisting of tightly crammed beta sheets. Other mechanisms may exist within yet undiscovered infectious protein particle.

prions are a group of proteinaceous viruses that own rna as the genetic material.
they make happen mad-cow disease, kuru(laughing death) disease
alzheimer's disease, scrapie disease in sheep
yes they can reproduce but simply inside the body of the host

I thought prions were the founders of a priory.

it is a protein of virus.

reproduce by DNA transcription and translation

Prions are smaller and simpler than viruses.
They can reproduce and inflict disease
They are typically resistant to standard sterilization techniques
