What are the two components of chromosome ?

Answer

**Step-by-Step Solution:**

1. **Understanding Chromosomes**: Chromosomes are structures within cells that contain genetic material. They play a crucial role in storing and transmitting genetic information.

2. **Components of Chromosomes**: The two primary components of chromosomes are:
- **DNA (Deoxyribonucleic Acid)**: This is the molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.
- **Proteins**: Specifically, histone proteins are the key proteins associated with DNA in chromosomes. They help package the DNA into a compact, organized structure.

3. **Function of Histone Proteins**: Histone proteins play an essential role in the organization of DNA. They help in the winding and packing of DNA into a structure that can fit within the cell nucleus. This packaging is crucial for DNA to be properly managed during cell division and for gene expression.

4. **Conclusion**: Therefore, the two components of a chromosome are DNA and histone proteins.
