There are far too many odd words in biology. Genome (an organism's full complement of genetic information) and proteome (all the proteins prodeuced from the genes in the genome) I can cope with, even if people are still debating their exact definition. Things start getting silly when we get transcriptome, physiome, metabalome, morphome, phenome, interactome, glycome, secretome, ribonome, cellome, operome, transportome, pseudome, functome, translatome, foldome, unknome...
I think we need a new word - the omome - to describe the full collection of 'omes.
Despite the terrible pun in the title, see:
