How does the editing of trypanosome mitochondrial RNAs differ from that of mammalian genes?
What will be an ideal response?
Ans: While RNA editing of mammalian genes results in base substitutions, editing of RNAs in trypanosome mitochondria involves insertions, and sometimes deletions, of uridines. This results in a frameshift; the correct reading frame is not present in the original DNA.
