    I know the difference between these types, but why isn't human RNA polycistronic?

    If bacteria had evolved this capability, why wouldn't we?

    Humans have evolved more complex ways for regulating transcription.... with methylation/acetylation of histones, transcription factors, etc.... But you don't need to know poly/monocistronic for the MCAT

    Both ExamKrackers and the Berkeley Review go into some detail to describe the lac operon in bacteria, which is a polycystronic message. Might be worthwhile to understand it.
