Question

Quizplus · Accepted Answer

In RNA editing, adenine can be deaminated to inosine, and cytosine can be deaminated to uracil (not thymidine as stated in option A, but the concept of change is correct). These changes can indeed result in new codons, which can alter the protein produced. Therefore, answers A and C are correct, making D the correct choice.
