Wobble hypothesis proposes that the first two nucleotides of a triplet code specify an amino acid.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Triplet Code**: The genetic code is composed of triplet codons, where each codon consists of three nucleotides. Each triplet corresponds to a specific amino acid.

2. **Role of the First Two Nucleotides**: According to the wobble hypothesis, the first two nucleotides of a codon are crucial in determining which amino acid will be incorporated during protein synthesis. These nucleotides provide the primary specificity for the amino acid.

3. **The Third Nucleotide (Wobble Position)**: The third nucleotide in the triplet is known as the "wobble position." This position is less critical for the binding of the corresponding tRNA. It allows for some flexibility or "wobbling" in base pairing, meaning that it does not need to be a perfect match for the tRNA to bind effectively.
