Options

A. Richmond and Lang effect
B. Gene flow hypotesis
C. Wobble hypothesis
D. Transposability

Answer

To solve the question, "A single anticodon can recognize more than one codon of m-RNA. This phenomenon is termed as," we need to understand the relationship between anticodons and codons in the context of protein synthesis. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Codons and Anticodons**:
- Codons are sequences of three nucleotides on mRNA that correspond to specific amino acids.
- Anticodons are sequences of three nucleotides on tRNA that are complementary to the codons on mRNA.

2. **Recognizing the Phenomenon**:
- In the genetic code, some amino acids are coded by more than one codon. This means that a single tRNA molecule (with its anticodon) can pair with different codons on the mRNA.

3. **Identifying the Term**:
- The ability of a single anticodon to recognize multiple codons is known as "wobble." This phenomenon allows for flexibility in base pairing at the third position of the codon.

4. **Historical Context**:
- The wobble hypothesis was proposed by Francis Crick in 1966. It explains how the third position of the codon can tolerate mismatches, allowing for a single tRNA to pair with multiple codons.

5. **Evaluating the Options**:
- The options provided are:
- A) Richmond and Lange effect
- B) Gene flow hypothesis
- C) Wobble hypothesis
- D) Transposability
- Among these, the correct answer is C) Wobble hypothesis.

6. **Conclusion**:
- Therefore, the phenomenon where a single anticodon can recognize more than one codon of mRNA is termed the "wobble hypothesis."
