alleryWobble hypothesis explains:
AWhy DNA double helix wobbles in solution
BThe pairing flexibility at the **third** (3') position of a codon, which underlies degeneracy
CRandom codon assignment
DWhy tRNAs sometimes fail to bind ribosomes
Answer & Solution
Correct answer: B. The pairing flexibility at the **third** (3') position of a codon, which underlies degeneracy
**Crick's wobble hypothesis:** the first two codon positions pair strictly with the anticodon, but the third can wobble — allowing a single tRNA to recognise multiple codons differing in the 3rd base.
Explains why codons coding for the same amino acid often differ in the third base.
