The amino acid attaches to the tRNA at its

Options

A. 5'-end
B. 3'-end
C. Anti codon site
D. DHU loop

Explanation

To answer the question "The amino acid attaches to the tRNA at its," we need to identify the specific location on the tRNA molecule where the amino acid binds. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Structure of tRNA
tRNA (transfer RNA) is a molecule that helps in the translation of mRNA (messenger RNA) into proteins. It has a specific structure that includes an anticodon and an amino acid binding site.

**Hint:** Familiarize yourself with the basic structure of tRNA, including its anticodon and the ends of the molecule.

### Step 2: Identify the Ends of tRNA
tRNA has two important ends: the 5' end and the 3' end. The 3' end is crucial for the attachment of the amino acid.

**Hint:** Remember that the 3' end is typically where the amino acid is attached, while the 5' end is involved in other functions.

### Step 3: Locate the Amino Acid Binding Site
The amino acid binding site is located at the 3' end of the tRNA. This site is specifically designed to hold the amino acid that corresponds to the tRNA's anticodon.

**Hint:** Think about how the tRNA interacts with amino acids during protein synthesis and where this interaction occurs.

### Step 4: Recognize the Relationship with the Anticodon
The amino acid binding site is opposite the anticodon region. The anticodon is responsible for pairing with the corresponding codon on the mRNA during translation.

**Hint:** Visualize the tRNA structure to see how the anticodon and the amino acid binding site are positioned relative to each other.

### Step 5: Conclusion
Based on the structure and function of tRNA, we can conclude that the amino acid attaches to the tRNA at its **3' end**.

**Final Answer:** The amino acid attaches to the tRNA at its **3' end**.
