AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the name of the protein coat of a virus. 2. **Analyzing the Options**: - **Option 1: Prion**: A prion is a type of protein that can cause other proteins to misfold, particularly in the brain. It is not related to viruses, so this option is incorrect. - **Option 2: Capsomere**: A capsomere is a subunit of the capsid, which is the outer covering of the virus. While it is related to the structure of the virus, it is not the name of the protein coat itself. Thus, this option is also incorrect. - **Option 3: Capsid**: The capsid is the protein coat of the virus. It is made up of protein subunits called protomers and serves to protect the viral nucleic acid. This option is correct. - **Option 4: Mantle or Envelope**: The mantle or envelope refers to a layer of tissue found in mollusks and is not related to the protein coat of viruses. Therefore, this option is incorrect. 3. **Conclusion**: Based on the analysis of the options, the correct answer is **Capsid**, which is the protein coat of a virus. **Final Answer**: The protein coat of a virus is called the **Capsid**. ---
