The biology of [[self-replication]] is self-referential, as embodied by [[DNA]] and [[RNA]] replication mechanisms. Models of self-replication are found in [[Conway's Game of Life]] and have inspired engineering systems such as the self-replicating 3D printer [[RepRap]] . | The biology of [[self-replication]] is self-referential, as embodied by [[DNA]] and [[RNA]] replication mechanisms.
