The DNA in the cell........... is the information source for making proteins:

Options

A. Nucleus
B. Ribosome
C. Cell wall
D. Plasma membrane

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the location of DNA in the cell, which serves as the information source for making proteins.

2. **Identifying the Options**: The options provided are:
- Option 1: Nucleus
- Option 2: Ribosome
- Option 3: Cell wall
- Option 4: Plasma membrane

3. **Analyzing Option 1 - Nucleus**:
- The nucleus is the organelle in eukaryotic cells that contains the genetic material (DNA).
- DNA is responsible for storing and transmitting genetic information, which is essential for protein synthesis.

4. **Analyzing Option 2 - Ribosome**:
- Ribosomes are the sites of protein synthesis where the actual assembly of proteins occurs.
- However, ribosomes do not contain DNA and do not serve as the information source for making proteins.

5. **Analyzing Option 3 - Cell Wall**:
- The cell wall is a structural component that provides support and protection to the cell.
- It does not contain DNA and is not involved in the information source for protein synthesis.

6. **Analyzing Option 4 - Plasma Membrane**:
- The plasma membrane is the outer boundary of the cell that regulates what enters and leaves the cell.
- Like the cell wall, it does not contain DNA and is not involved in protein synthesis.

7. **Conclusion**: Based on the analysis, the only correct answer is Option 1: Nucleus, as it is where DNA is located and serves as the information source for making proteins.

### Final Answer:
The DNA in the cell **Nucleus** is the information source for making proteins.
