They are not biological and don't "replicate" in a biological sense. They are misshapen proteins and they cause other proteins to also become misshapen, and thus cells just come apart or die.

How could prions multiply without nucleic acids?
Prions multiply by a process which is, at present, not fully understood. The protein PrPr is present in healthy cells of all mammals, in the brain and central nervous system. It is only when the gene that creates PrPr undergoes mutation that it begins to produce a harmful strain of PrPr, the prion. Prions replicate by causing the surrounding healthy proteins to fold abronmally, turning them into prions. These newly-formed prions in turn cause other proteins to fold abnormally. This process creates vacuoles in the cells of the brain, resulting in diseases such as Creutzfeld-Jakob disease in humans, and Bovine Spongiform Enphysema in cows.

How does the cell replicate DNA?
Cells do not replicate "In DNA". Cells replicate their DNA during the process of cell division.
How do cells Replicate?
Cells replicate for many reasons, they replicate by a process of mitosis or meiosis. Mitosis producing two daughter cells and meiosis producing gamete cells (sperm or ovum(egg) )
Which best describes how common cold spread in the human body?
viruses replicate inside respiratory cells.
How do prions reproduce?
They don't quite 'reproduce', propagate would be closer to the mark. Prions are 'rogue' proteins, versions of naturally occurring proteins with a different 3D structure. They replicate in living host .
Why do chromosomes replicate?
They replicate to form two identical daughter cells.
Do lung cells replicate?
All cells reproduce.
How many cells are replicated?
15,000,000 cells replicate in the body?
Do flamingos have cells?
Yes, all animals and plants that exist have cells. The only living things that do not have cells are viruses and perhaps prions.
What is a protein that can cause infection or disease?
Prions can cause an infection. They are simple proteins that can replicate under the right circumstances and one of them causes Mad Cow disease.
How cell replication?
Cells replicate for many reasons, they replicate by a process of mitosis or meiosis. Mitosis producing two daughter cells and meiosis producing gamete cells (sperm or ovum(egg) )
Paritcle of nucleic acid and protien that can reproduce only by infecting living cells?
prions
