Which of the following shows coiled RNA strand and capsomeres

Options

A. Retrovirus
B. Polio virus
C. Tabacco mosaic virus
D. Measles virus

Answer

To solve the question "Which of the following shows coiled RNA strand and capsomeres?", we can follow these steps:

### Step 1: Understand the Terms
- **Coiled RNA Strand**: This refers to the genetic material of certain viruses, which can be in the form of RNA that is coiled or helical.
- **Capsomeres**: These are the protein subunits that make up the capsid, which is the protective outer shell of a virus.

### Step 2: Identify the Virus
- The question is likely referring to a specific virus that has both coiled RNA and capsomeres. One well-known virus that fits this description is the Tobacco Mosaic Virus (TMV).

### Step 3: Analyze the Structure of TMV
- The Tobacco Mosaic Virus has a helical structure, where the RNA is coiled within a protein coat. The protein coat is composed of capsomeres, which are the building blocks of the capsid.

### Step 4: Conclusion
- Based on the information about the Tobacco Mosaic Virus, we can conclude that it is the virus that shows both a coiled RNA strand and capsomeres.

### Final Answer
- The correct option is **Tobacco Mosaic Virus**.
