The biology
Lambda phage has two modes: lytic (make ~100 copies and burst the cell) or lysogenic (integrate quietly and pass to all descendants). The choice is a bistable switch at the OR operator: the CI repressor binds cooperatively, regulates its own synthesis, and holds lysogeny; Cro binds the same operators in the opposite order and drives lysis. Lysogeny is stable for many generations yet inducible — DNA damage activates RecA, which triggers cleavage of CI and flips the switch.
A switch that holds a memory
Here the switch remembers: once thrown to lysogeny it stays, through hundreds of divisions, because CI keeps making CI — a self-sustaining state of the address, held stable until a signal (damage, via RecA) flips it. This is memory written into a coordinate: not a passive mark but an actively maintained reading, the field holding one interpretation of the address until the conditions call for the other. The 12-base complementary cos ends close the linear DNA into a circle in the cell.
Where this departs from current science
| Current science says | The Force of Time says |
|---|---|
| The lysis/lysogeny switch is a gene-regulatory bistability. | It is a maintained reading of the address — a memory the field holds until a signal flips it. |
| Induction is CI cleavage by activated RecA. | It is the signal that flips a remembered coordinate from one stable reading to the other. |
