Recently, I've been studying some alien biology. It turns out that alien DNA is surprisingly close to ours - they have all of the same amino acids, all coded the same way. I've found one important difference, however: in aliens, selenocysteine and pyrrolysine are always coded by their respective codons. This means that aliens only have one STOP codon.

I've been working on these two DNA fragments for a while, and I don't know where to go from here. Do you think you can help?
