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.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
