Engineers fabricate things but things sometimes are just too complicated

Engineers like to hide things In Engineering there are a few important

guiding concepts.

Polymerase Per SecondsPolymerase Per Seconds

Abbreviation - PoPS Analogous to current in electrical circuits Polymerase per seconds is the flow of RNA

polymerase molecules along DNA

PoPSPoPS

Current is the flow of electrons, literally number of electrons per second

PoPS level aka current level is set by the amount of RNA polymerase molecules that trundle past a specific position on DNA each second.

Signals in biological circuits is carried by the PoPS.
