Prions are too poorly understood to give a definitive answer on this. However it is believed that the normal version of the protein (PrPC) resides on the cell membrane and is involved in cell to cell communication. So it's likely that the prions don't enter the cytoplasm.

How do prions get into a cow's brain?
Prions can enter a cow's brain through consumption of contaminated feed or by contact with infected bodily fluids. Once in the brain, prions cause misfolding of normal proteins, leading to the progression of diseases like BSE (mad cow disease).
What structure allows RNA to enter the cytoplasm?
Nuclear Pores
How do prions act?
Prions are misfolded proteins that can induce other proteins to misfold in a similar manner. These misfolded proteins can gather together and accumulate in the brain, leading to the formation of plaques that can cause neurodegenerative diseases like Creutzfeldt-Jakob disease. Once prions enter the body, they can spread and infect other cells, perpetuating the cycle of misfolded protein accumulation.
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.
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.

Cytoplasm holds all the organelles in place.

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.
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.
Do prions contain DNA or RNA?
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.
How do materials enter and exit a cell and keep the necessary cytoplasm within the cell membrane?

How are viroids and prions the same?
Both Viroids and Prions have nucleic acid, but Viroids have no outer protein coat.
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.
