Which of the following is a true statement regarding the process of RNA editing?
A. RNA editing alters the sequence of the mRNA message thereby permitting for an enhance in protein diversity without increasing the size of the genome.
B. RNA editing enzymes can change the identity of each of the four RNA nucleotides (adenine, guanine, cytosine and uracil).
C. RNA editing enzymes can change the sequence of DNA thereby permanently incorporating sequence changes into the genome.
D. RNA editing enzymes will alter the sequence of the intron-exon junction thereby resulting in the alternate use of exons.
