You are characterizing the properties of a self-splicing ribozyme and obtain the following
Results: in the presence of Mg²⁺, self-splicing occurs. However, in the absence of Mg²⁺, self-splicing does not occur. Which of the following hypotheses does this observation support?

Question

Quizplus · Accepted Answer

The observation that self-splicing occurs in the presence of Mg²⁺ but not in its absence suggests that Mg²⁺ acts as a cofactor necessary for the ribozyme's activity.
