How can you deduce the nature of an alien genetic code? You've determined that the RNA consists of the usual letters, A, C, G, and U. But are they grouped in a fixed-length code? If so, how long is the unit? Or is the unit of variable length? Do codons overlap? What codon-amino acid equivalences can you deduce?

Here are the tools available to you, all found on the FUNCTION menu (if you've ENTERed alien-world). Click on them to find out how to use them:
