Noncanonical base pairings are observed between the third position of the codons and the first position of the anticodons.This concept is known as the
A) nonsense rule.
B) noncanonical hypothesis.
C) wobble hypothesis.
D) 3:1 hypothesis.

Question

Quizplus · Accepted Answer

The concept described in the question is known as the wobble hypothesis, where noncanonical base pairings (such as G-U or inosine) are allowed between the third position of the codons and the first position of the anticodons. This allows for greater flexibility in the genetic code, and reduces the number of tRNAs needed to read all 61 codons. The other answer choices (nonsense rule, noncanonical hypothesis, 3:1 hypothesis) do not accurately describe the concept in the question.
