Polymerase Per Seconds Abbreviation - PoPS Analogous to current in electrical circuits Polymerase per seconds is the flow of RNA polymerase molecules along DNA Abbreviation - PoPS Analogous to current in electrical circuits Polymerase per seconds is the flow of RNA polymerase molecules along DNA
PoPS 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.
