t-RNA can also be called

Options

A. s RNA
B. adaptor RNA
C. interpretor of genetic code
D. genetic RNA

Answer

To determine what t-RNA can also be called, we can analyze the options provided and the function of t-RNA in the process of protein synthesis.

### Step-by-Step Solution:

1. **Understanding t-RNA**: t-RNA, or transfer RNA, is a type of RNA molecule that plays a crucial role in translating the genetic code from mRNA into proteins. It carries amino acids to the ribosome, where proteins are synthesized.

2. **Analyzing the Options**:
- **Option A: sRNA**: This refers to small RNA, which is not synonymous with t-RNA.
- **Option B: Adapter RNA**: This suggests that t-RNA acts as an adapter between mRNA and amino acids, which aligns with its function.
- **Option C: Interpreter of Genetic Code**: While t-RNA does interpret the genetic code, this term is not commonly used to refer to t-RNA specifically.
- **Option D: Genetic RNA**: This is a vague term and does not specifically refer to t-RNA.

3. **Identifying the Correct Answer**: Given that t-RNA serves as a mediator (or adapter) between the mRNA codons and the corresponding amino acids during protein synthesis, the most accurate term for t-RNA from the provided options is **Adapter RNA**.

4. **Conclusion**: Therefore, the correct answer is **Option B: Adapter RNA**.
