Chapter Twelve, Self-Assembly
This chapter relates to how understanding the genetic code matches models for embryonic development among vertebrates. Ridley discusses 'gap' genes, 'pair-rule' genes, and 'segment-polarity' genes. Homeotic genes and Hox genes are described briefly. Walter Gehring's discovery of the homeobox set of codes in 1983 is related to an on and off switch metaphorically.
