The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Hind II**: Hind II is identified as a restriction endonuclease. This means it is an enzyme that cuts DNA at specific sequences. 2. **Nature of Hind II**: It is important to note that Hind II is a protein. Enzymes, including restriction endonucleases, are proteins that facilitate biochemical reactions. 3. **Analyzing the Options**: - **Option A: Polynucleotide** - This refers to a polymer of nucleotides, which makes up nucleic acids like DNA and RNA. This option is incorrect. - **Option B: Polypeptide** - This refers to a polymer of amino acids, which are the building blocks of proteins. Since Hind II is a protein, this option is correct. - **Option C: Polysaccharide** - This refers to polymers of monosaccharides, which are carbohydrates. This option is incorrect. - **Option D: Bacterium** - This refers to a single-celled organism. Since Hind II is an enzyme and not a living organism, this option is also incorrect. 4. **Conclusion**: The correct answer is that Hind II is a polypeptide (protein). **Final Answer**: Hind II is a polypeptide (protein). ---
