Bacteriophage is made up to

Options

A. Carbon and nitrogen
B. DNA
C. Nucleoprotein ( Nucleic acid + protein )
D. Protein only

Answer

**Step-by-Step Solution:**

1. **Understanding Bacteriophages**:
- Bacteriophages are viruses that specifically infect bacteria. They are a type of virus that targets bacterial cells.

2. **Composition of Bacteriophages**:
- Bacteriophages are primarily composed of two main components:
- **Nucleic Acid**: This can either be DNA or RNA, but not both. The genetic material carries the information necessary for the virus to replicate and infect host cells.
- **Protein Coat (Capsid)**: This is a protective layer that surrounds the nucleic acid. The protein coat is made up of proteins that help in the protection of the genetic material and assist in the attachment and entry into the bacterial host.

3. **Elements Present in Bacteriophages**:
- In addition to nucleic acids and proteins, bacteriophages also contain elements such as carbon and nitrogen, which are fundamental components of both nucleic acids and proteins.

4. **Conclusion**:
- Therefore, the correct answer regarding the composition of bacteriophages is that they are made up of nucleoproteins, which consist of nucleic acids (DNA or RNA) and proteins.

**Final Answer**: Bacteriophage is made up of nucleoproteins, which include DNA or RNA and proteins.
