Amino acid acceptor end of tRNA lies at

Options

A. 5' end
B. 3' end
C. `TPsiC` loop
D. DHU loop

Answer

To solve the question regarding the location of the amino acid acceptor end of tRNA, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of tRNA**:
- tRNA (transfer RNA) is a type of RNA molecule that helps in the translation process by bringing amino acids to the ribosome. It has a specific structure that includes an anticodon loop and an amino acid acceptor end.

2. **Identify the Anticodon Loop**:
- The anticodon loop is a region of tRNA that contains a sequence of three nucleotides (the anticodon) that is complementary to the mRNA codon. This allows the tRNA to recognize and bind to the correct codon during protein synthesis.

3. **Locate the Amino Acid Acceptor End**:
- The amino acid acceptor end is the site on the tRNA where the amino acid attaches. This end is crucial for the tRNA's function in protein synthesis.

4. **Determine the Position of the Amino Acid Acceptor End**:
- The amino acid acceptor end is located at the 3' end of the tRNA molecule. This is opposite to the anticodon loop, which is typically found at the 5' end of the tRNA.

5. **Conclude the Answer**:
- Therefore, the amino acid acceptor end of tRNA lies at the 3' end.

### Final Answer:
The amino acid acceptor end of tRNA lies at the **3' end**.
