Explanation

### Step-by-Step Solution

**Step 1: Definition of Transcription**
Transcription is the biological process through which the genetic information encoded in DNA is copied into messenger RNA (mRNA). This process is essential for the synthesis of proteins, as mRNA serves as a template for translation.

**Step 2: Components Involved in Transcription**
- **DNA Template**: The segment of DNA that contains the genes to be transcribed.
- **RNA Polymerase**: The enzyme responsible for synthesizing mRNA from the DNA template. The specific type used in this process is called DNA-dependent RNA polymerase.
