What did comparing the sequence of the mitochondrial genome in trypanosomes with the sequence of mature mitochondrial RNAs demonstrate?

A)The RNA sequences are similar to the genome sequence, but have insertions and deletions of uracil residues.
B)The RNA sequences align perfectly with the genomic DNA from which it is transcribed.
C)All of the proteins necessary for translation are encoded in the mitochondrial genome.
D)Translation is initiated in mitochondria only at AUG codons.
E)Some mature RNAs do not have start and stop codons.
