Chapter 25 Multiple Choice Question 9

Part A

Which of the following BEST explains the "wobble" hypothesis proposed by Francis Crick?

Which of the following BEST explains the "wobble" hypothesis proposed by Francis Crick?

The genetic code is degenerate in that most amino acids have more than one codon. Inosine can pair up with A, U, or C. The anticodon can pair with any part of the corresponding codon. The 5' base of the anticodon can make non Watson-Crick hydrogen bonds with several different bases at the 3' position of the codon. The genetic code is ambiguous in that each codon can specify more than one amino acid.

Explanation / Answer

The 5' base of the anticodon can make non Watson-Crick hydrogen bonds with several different bases at the 3' position of the codon.

This pairing is called as wobble pairing and is the main explanation for degeneracy of the codon.
