Wobble hypothesis explains which one of the following properties of genetic code?
Options
- AGenetic code is universal.
- BGenetic code is non-ambiguous.
- CGenetic code is commaless.
- DDegeneracy of genetic code.
Correct answer
D. Degeneracy of genetic code.
Step-by-step solution
The Wobble hypothesis, proposed by Francis Crick, explains the degeneracy of the genetic code. It states that the third base of a codon can form non-standard base pairs with the first base of the anticodon on the tRNA. This flexibility (wobble) allows a single tRNA molecule to recognize and bind to more than one codon, which explains why multiple codons can code for the same amino acid (degeneracy). Answer: Degeneracy of genetic code.
