Question

Find all ORFs in human, chimp and mouse mtDNA (GenBank accession
numbers respectively NC 001807, NC 001643 and NC 005089). Note that
the genetic code for mitochondria is slightly different from the standard one.
In particular the one for vertebrates has different start and stop codons,
resulting in different ORFs: the codon TGA means stop in the universal
code, but codes for tryptophan in mtDNA; AGA and AGG code for arginine
in the universal code and the stop codon in mtDNA; and ATA represents
isoleucine in the universal code and methionine in mtDNA. What fraction
of the sequence repre
