From genomics to proteomics, metagenomics and beyond

Genomics are blueprints; proteomics are working molecular machines. And if we consider a person as a symbiotic superorganism, we will also have to do metagenomics – the study of genes (and proteins?) gut microbiota. But there is also metabolomics, and many others -omics…
