What will be the next product in the process shown below?
DNA `rarr` RNA `rarr`?

Options

A. mRNA
B. tRNA
C. rRNA
D. Protein

Answer

To determine the next product in the process outlined in the question, we will follow the steps of the central dogma of molecular biology, which describes the flow of genetic information within a biological system.

### Step-by-Step Solution:

1. **Understanding the Central Dogma**: The central dogma of molecular biology explains the flow of genetic information from DNA to RNA to protein. It consists of three main processes: replication, transcription, and translation.

2. **Identifying the First Step**: The first step in the central dogma is **replication**, where DNA is copied to produce more DNA. However, this step is not relevant to the question since it starts with DNA already.

3. **Identifying the Second Step**: The second step is **transcription**, where the DNA sequence is transcribed to produce messenger RNA (mRNA). This is represented in the flow as:
- DNA → RNA (specifically mRNA).

4. **Identifying the Next Step**: The third step is **translation**, where the mRNA is translated into a protein. This is represented as:
- RNA → Protein.

5. **Conclusion**: Since the question asks for the next product after RNA, we conclude that the next product in this process is **protein**.

### Final Answer:
The next product in the process shown is **protein**.
