A sequence of three consecutive bases in a tRNA molecule specifically binds to a complementary codon sequence in mRNA. This sequence is known as:

Options

A. Triplet
B. Non-sense codon
C. Anticodon
D. Termination codon

Answer

To solve the question regarding the sequence of three consecutive bases in a tRNA molecule that specifically binds to a complementary codon sequence in mRNA, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Codons and Anticodons**:
- In molecular biology, a codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.
- tRNA (transfer RNA) has a region known as the anticodon, which is also a sequence of three nucleotides.

2. **Role of tRNA in Translation**:
- During the process of translation, tRNA molecules bring amino acids to the ribosome, where they match their anticodons with the codons on the mRNA strand.
- This complementary binding ensures that the correct amino acid is added to the growing polypeptide chain.

3. **Identifying the Correct Term**:
- The question specifically asks for the sequence in tRNA that binds to the codon in mRNA.
- Since the three consecutive bases in tRNA that pair with the mRNA codon are referred to as the anticodon, we can conclude that this is the term we are looking for.

4. **Conclusion**:
- Therefore, the sequence of three consecutive bases in a tRNA molecule that specifically binds to a complementary codon sequence in mRNA is known as the **anticodon**.

### Final Answer:
The correct answer is **anticodon**.
