Paritcle of nucleic acid and protien that can reproduce only by infecting living cells?
prions
Describe how can viruses and prions can alter cell function?
Viruses can alter cell function by entering host cells and using their machinery to replicate and produce more virus particles. Prions, on the other hand, are misfolded proteins that can induce normal proteins in the cell to also misfold and accumulate, disrupting normal cellular function. Both viruses and prions can cause damage to cells, leading to various diseases and health problems.
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 aren't prions alive?
This could be a real gray area depending on the definition of life.I would have to say yes as they meet the following criteria.they reproduce.they employ enzymes (themselves)they utilized energy to perpetuate their functionthey utilized resources to perpetuate their function.
Can you kill prions by sterilization?
No, cooking does not destroy or disable prions. If you were able to cook a meat that contains prions to the point where the prions were disabled, the meat would be rendered inedible.You can use chemicals mixed with heat to destroy prions, but that's not a process you would want to subject your food to.

prions
Why don't viruses and prions qualify as organisms?
Both are missing some key characteristics of life - prions more so than viruses. The most prominent feature that is missing is the ability to reproduce without a host. Viruses can't reproduce without a host cell and prions can't propagate without a normal protein that is transformed into a prion.

What is the cycle map on how prions replicate?
Prions replicate by converting normal cellular proteins into misfolded prion proteins. The misfolded proteins then template the conversion of more normal proteins into prions. This cycle results in the accumulation of prions in the brain, leading to neurodegeneration.
What is a nonliving thing that reproduces?
It is somewhat doubtful whether viruses and prions can be considered living things. They have some characteristics of living things, but lack others.A fire can reproduce. Several types of computer programs, and especially malicious programs, can reproduce. I believe some of the figures in Conway's Game of Life can reproduce.
Can hydroxyls kill prions?
Hydroxyl radicals have been shown to degrade and inactivate prions by breaking down their protein structure. This process can help reduce the infectivity of prions in the environment.
How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
Do prions contain DNA or RNA?
Prions are an infectious particle made of protein. They do not contain DNA or RNA.
Do prions have RNA?
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.
