It is important that the whole general “hyper-cycle” be closed, i.e. that there is an En which feeds back on I1. Thus the system represents a “cyclic hierarchy” in which many cyclic (complementary) nucleotide collectives are linked together by an enzymic “hyper-cycle”. This secondary loop closure is important, since otherwise the different Ik would not cooperate but compete and thus select against each other.
