The Chromosomes Genomical by Bradypus We have the very model of the chromosomes genomical The implications of this feat are really astronomical We've sequenced every human gene, at least ninety percent of them Intelligent and cunning too, and using every stratagem We've introns, exons, codons, genes and bases found in DNA We've duplicated, replicated, translated it for many a day It's published on the net, and in the scientific literature We know we've made our mark, and that our science now is fit for sure Chromosomes one to twenty-two, and X and Y, there are no more Are just arrangements of the bases, and of these there's only four These bases, paired on DNA, contain all that you need to know For proteins, livers, hearts and brains and anything you want to grow With letters four the code is made, the letters A, C, G and T A pairs with T, and G with C, so replication works you see ATTAC ATTAC A GAG A CAT may not mean much to human eyes But in your genes the code is clear, more powerful than you realise The DNA makes RNA, that's carried to the ribosome And there the processes take place to make use of the chromosome Three bases at a time are read, an amino acid specified Then piece by piece the protein's built, the logic cannot be denied From smallest cell to largest bone, the human body bit by bit Is built from proteins, or at least a protein is involved in it And so you see, both you and me, although the notion's comical Are made and shaped and live and die by instructions genomical So if your eyes are brown or blue, and if your hair be thick or thin And if your blood is A or O, and what's the colour of your skin Your chromosomes have made it so, there's nothing left for you to do But pass them on, your genes will live in generations after you A single letter wrong passed on, in future that could spell bad news That's how genetic defects come, the future genome to confuse And so we think genes cause disease, but that is not the whole of it More oft than not things work out right, and that's what keeps the species fit. You'd think that now the genome's read, there's nothing left for us to do The truth is very different, let me tell you of this point of view We know the genes, but by and large we don't yet know what role they play There's still a lot of work to do to see exactly what they say And there's more to life than genes, for we react to our environment So predestination doesn't come just from the genome's government We're still free souls to choose, and our choice would be quite comical If we did nothing more now that we've cracked the code genomical
