title: The triplet code: is it enough?
abstract: It is suggested that the triplet code dogma that the role of DNA as an information carrier can only be defined in terms of a code for amino acids embodied in the sequence of nucleotides, is inadequate to encompass the totality of information/instruction/organisation necessary for the maintenance of living systems. It is proposed that, as a minimum, a second independent but complementary mechanism is necessary involving direct DNA--DNA intercommunication. Further, that this mechanism may operate on the basis of a chemically switched microprocessor network system with individual DNA sequences able to act as individual microprocessors.
