What is the function of a viral capsid?
Correct answer: D. All of the above
- A. Protection against the viral genome from physical and enzymatic destruction.
- B. Providing binding sites that enable the virus to attach to specific receptor sites on the host cell.
- C. Serving as a vehicle of transmission from one host to another.
- D. All of the above
Explanation
The viral capsid is a protein shell that protects the viral genome from damage and enzymatic degradation, allows the virus to attach to specific host cell receptors, and helps transmit the virus between hosts. It is essential for safeguarding the genome, enabling infection, and supporting viral spread.
