The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding RNA Polymerase III**: RNA polymerase III is one of the three main types of RNA polymerases found in eukaryotic cells. It is primarily responsible for synthesizing certain types of RNA. 2. **Identifying the Types of RNA Synthesized**: RNA polymerase III synthesizes several types of RNA, including: - Transfer RNA (tRNA) - 5.8S ribosomal RNA (rRNA) - Small nuclear RNA (snRNA) - Other small RNAs 3. **Focusing on tRNA**: Among these, the most significant and well-known product of RNA polymerase III is tRNA. tRNA plays a crucial role in translation, where it helps in the synthesis of proteins by bringing amino acids to the ribosome. 4. **Role of tRNA in Protein Synthesis**: tRNA is essential for translating the genetic code from mRNA into a sequence of amino acids, which ultimately forms proteins. This process is vital for cell function and growth. 5. **Conclusion**: Therefore, the primary synthesis product of RNA polymerase III is tRNA, which is crucial for protein synthesis. **Final Answer**: RNA polymerase III synthesizes tRNA. ---
