RNA plays an important role in `:`

Options

A. cell division
B. protein synthesis
C. protein digestion
D. carbohydrate synthesis

Answer

### Step-by-Step Text Solution:

1. **Understanding RNA**: RNA stands for ribonucleic acid. It is a nucleic acid that plays a crucial role in the process of translating genetic information from DNA into proteins.

2. **Transcription Process**: The first step in the flow of genetic information is transcription, where the DNA sequence is transcribed into RNA. This process results in the formation of messenger RNA (mRNA) from the DNA template.

3. **Translation Process**: After transcription, the next step is translation. During this process, the mRNA is translated into a specific sequence of amino acids, forming a protein. Each set of three nucleotides in the mRNA, called a codon, corresponds to a specific amino acid.

4. **Role of Codons**: Codons are crucial as they dictate the sequence of amino acids in a protein. The information carried by the RNA is read in sets of three nucleotides, which ultimately determines the structure and function of the resulting protein.

5. **Conclusion**: Based on the processes of transcription and translation, it is clear that RNA plays a significant role in protein synthesis. Therefore, the correct answer to the question "RNA plays an important role in:" is **protein synthesis**.
