Worked Solution & Example Answer:A prion is a form of A - VCE - SSCE Biology - Question 5 - 2004 - Paper 1
Step 1
Identify the correct answer
Answer
To determine what a prion is a form of, we need to evaluate the definitions of each option:
- A. DNA: This is the genetic material found in living organisms, but prions are not composed of nucleic acids.
- B. virus: While viruses can cause diseases, prions are distinct from viruses as they lack nucleic acids.
- C. protein: Prions are misfolded proteins that can induce other normal proteins to also misfold, thus they are indeed a form of protein.
- D. bacterium: Bacteria are single-celled organisms that contain both DNA and RNA; prions do not pertain to bacterial structure.
Given this evaluation, the correct answer is C. protein.
