Question:
Wobble hypothesis explains which one of the following properties of genetic code?
Wobble hypothesis explains which one of the following properties of genetic code?
Show Hint
Wobble pairing lets one tRNA read several codons that differ at the third base.
Updated On: Nov 12, 2026
- Genetic code is universal.
- Genetic code is non-ambiguous.
- Genetic code is commaless.
- Degeneracy of genetic code.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Crick's wobble hypothesis says that the third base of a codon pairs loosely with the first base of the anticodon.
Step 2: Effect
Non-standard pairs such as G-U are allowed, so one tRNA can read more than one codon for the same amino acid.
Step 3: Link to the genetic code
This explains why most amino acids are coded by more than one codon, which is the degeneracy of the code.
Final Answer:
The wobble hypothesis explains the degeneracy of the genetic code. \[ \boxed{\text{(D) }\text{Degeneracy of genetic code}} \]
