Understanding Prions

The video introduces prions, infectious proteins known for causing diseases like mad cow disease. It explains the importance of correct protein folding for functionality and how prions, being misfolded proteins, can induce misfolding in normal proteins, leading to cellular damage. The video also highlights the need for further research into prions and their role in diseases such as Classic CJD and other neurodegenerative conditions.

What type of infectious agent are prions?

• Bacteria

• Virus

• Protein

• Fungus

What is the main issue with prions compared to normal proteins?

• They are not functional

• They are too large

• They are misfolded

• They are too small

What can happen when prions enter a cell with correctly folded proteins?

• They dissolve the proteins

• They cause proteins to misfold

• They have no effect

• They repair the proteins

Which human disease is mentioned as being caused by prions?

• Alzheimer's disease

• Parkinson's disease

• Classic CJD

• Multiple sclerosis

What are scientists exploring about prions?

• Their ability to cure diseases

• Their involvement in neurodegenerative diseases

• Their role in bacterial infections

• Their use in food production
