Explanation

### Step-by-Step Text Solution

**Step 1: Identify the information source for protein synthesis in the cell.**
- The primary source of information for making proteins in the cell is the DNA (Deoxyribonucleic Acid). DNA is located in the nucleus of the cell and serves as the genetic material that contains the instructions for protein synthesis.

**Step 2: Explain the process of protein synthesis.**
- The process of protein synthesis involves two main steps: transcription and translation.
- **Transcription:** This is the first step where the information from the DNA is transcribed into messenger RNA (mRNA). This occurs in the nucleus.
