Question
**Understanding Genes within Chromosomes in the Nucleus**

**Diagram Explanation:**
The image shows five labeled structures (A, B, C, D, E) depicting various components of a cell and its genetic material. 

- **Structure A** represents a single chromosome, which consists of tightly coiled DNA and proteins.
- **Structure B** shows a chromatid, one of the two identical halves of a replicated chromosome.
- **Structure C** details a segment of a DNA molecule, highlighting a gene section.
- **Structure D** illustrates a nucleus, which houses the cell's chromosomes.
- **Structure E** provides a broader view of the entire length of DNA within a chromosome.

**Questions and Answers:**

1. **Identify the Structures:**
   a. The cell: __________
   b. The DNA: __________
   c. A gene: __________
   d. The nucleus: __________
