Now the philosophy touches the body. DNA is the physical, material record of a life — opposites paired and written in a four-letter alphabet.
Our DNA is a strand of opposites, created by energy.
The human genome contains ~3.3 billion pairs, held together by hydrogen bonds.
The double helix is Chapter I made flesh: a strand of paired opposites, each rung an attraction held by a bond. The base letters T, A, G and C only mean anything in pairs — the code is written entirely in relationships, never in single things.

Genes are data that combine to form DNA.
Sort the possibilities and you get a small, fixed set — the six combinations of male/female and dominant/recessive. Every animal is treated as half male and half female, a negotiated settlement between two parents' data. Heredity is opposites, shuffled and re-paired.
