This type of RNA provides the template for protein synthesis

Options

A. m RNA
B. t RNA
C. r RNA
D. s RNA

Answer

**Step-by-Step Solution:**

1. **Understanding the Types of RNA**:
- There are several types of RNA involved in the process of protein synthesis: mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosomal RNA), and others like sRNA (small RNA).

2. **Identifying the Role of mRNA**:
- mRNA is specifically responsible for carrying the genetic information from DNA to the ribosome, where proteins are synthesized. This process is known as transcription, where mRNA is formed from a DNA template.

3. **Transcription Process**:
- During transcription, the DNA unwinds and one of the strands serves as a template for synthesizing mRNA. The mRNA strand is complementary to the DNA template strand.

4. **Translation Process**:
- After mRNA is synthesized, it moves to the ribosome, where translation occurs. In this stage, the mRNA serves as a template for assembling amino acids into a polypeptide chain, which eventually folds into a functional protein.

5. **Examining Other RNA Types**:
- tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the codons on the mRNA during translation.
- rRNA (ribosomal RNA) is a component of the ribosome and plays a crucial role in protein synthesis but does not serve as a template.
- sRNA (small RNA) is involved in regulating gene expression and does not directly participate in protein synthesis.

6. **Conclusion**:
- Based on the functions of the different types of RNA, the type of RNA that provides the template for protein synthesis is mRNA.

**Final Answer**: The type of RNA that provides the template for protein synthesis is **mRNA (messenger RNA)**.
