The interactive yes-no actions, modeling elementary bits, reveal
information as phenomenon of interaction. The impulse encoding merges
memory with the time of memorizing information and compensates the
memory cost by running time intervals of encoding. Multiple interactions
generate a code of the interacting process. In natural processes,
interacting through impulses with gradient of temperatures, emerges
information and physical process producing code analogous to DNA. The
found mathematical, information, and thermodynamic conditions of
generation logical information bits, their memorizing and encoding in
helix triplet code.
