Elucidating Principles of Gene Regulation from Stochastic Models
... The complexity of multicellular organisms arises largely from reusing many of the same genes in numerous combinations, rather than by the introduction of novel genes for each new celltype. Put another way, what makes you human is not so much which genes you have but how you use them. The instruction ...
