A sequence of three consecutive bases in a t-RNA molecule which specifically binds to a complementary codon sequence in m RNA is known as _

Options

A. Triple codon
B. Non- sense codon
C. Anti codon
D. Termination codon

Answer

To solve the question, we need to identify the specific term that describes a sequence of three consecutive bases in a tRNA molecule that binds to a complementary codon in mRNA.

### Step-by-Step Solution:

1. **Understanding tRNA and mRNA**:
- tRNA (transfer RNA) is a type of RNA that helps in the translation process by bringing amino acids to the ribosome, where proteins are synthesized.
- mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

2. **Identifying the Role of tRNA**:
- The tRNA molecule has a specific region that can recognize and bind to a complementary sequence on the mRNA. This is crucial for ensuring that the correct amino acid is added to the growing polypeptide chain.

3. **Defining the Binding Sequence**:
- The sequence of three bases in the tRNA that pairs with the three bases (codon) in the mRNA is essential for accurate translation. This sequence in tRNA is known as an "anticodon".

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

### Final Answer:
The sequence of three consecutive bases in a tRNA molecule which specifically binds to a complementary codon sequence in mRNA is known as **anticodon**.
