Quizplus · Accepted Answer

RNA editing involves enzymes that change the base sequence of the primary RNA transcript, leading to changes in the protein for which it codes. Option A is incorrect because spliceosomes do not change the base sequence of the RNA transcript, they only remove introns and join exons together. Option B is incorrect because different spliceosomes can generate different variants of the same RNA transcript by splicing different exons together, but not by changing the base sequence of the RNA. Option D is incorrect because microRNAs are not involved in RNA editing, they regulate gene expression by binding to RNA transcripts and preventing their translation into protein. Option E is incorrect because spliceosomes and enzymes have different functions in RNA processing, and they do not work in combination to modify the same RNA molecule.
