From Ron Partridge
Claire Ainsworth observes that “blueprint” is a lousy metaphor for what DNA does (13 June, p 42). The more that we have discovered about how genes function, the more the genome seems like an orchestra, performing a composition in successive movements. But the dynamism and interaction is something like an improvised jazz performance.
Maybe we can think of the development of an organism as a classical jazz symphony, performed by a very large group.
