A novel, alternative and deeper view to the "selfish gene" paradigm is presented, describable as the "selfish code" frame. Introducing it, we put forth a quantum mechanical algorithm as a new description of the intracellular protein synthetizing machinery. The successive steps of the algorithm are, tentatively, semiotic constraints of the well-known quantum mechanical molecular "internal measurement" type. It is proposed that this molecular algorithm mediates a quantum mechanical time reversed dynamics with a primordial special version of this latter molecular measurement type ("mixed measurement") as its origin. It is furthermore suggested that this intracellular regressive algorithmical dynamics is a component of biological "motion", the other, strongly coupled component being the macroscopic phenotypic motion. The biological "invariant of motion" of this hierarchically coupled overall generalized dynamics is suggested to be the evolutionally converged invariant genetic code vocabulary. It forms, possibly, the underlying internal "driving force" of evolution, as being "struggle for life".

The prothoracic gland (PGL) of Galleria mellonella is a Y-shaped, paired organ, consisting of 45-50 polyploid giant cells. The PGL cells are supplied by neurosecretory axons; release of neurosecretory granules (1000-1300 A in diameter) directly on the surface of PGL cells was frequently observed. Based on ultrastructure, the last two larval instars can be divided into three phases: 1) restitutive phase immediately after moulting; 2) gradual activation in mid-intermoult as indicated by the logarithmic cell growth, decrease of nucleo-cytoplasmic ratio, increase in the number of cell organelles participating in protein synthesis, and the structural changes of these organelles; 3) "release' period preceding moulting, characterized mainly by the extreme dilatation of peripheral invaginations. From the prepupal stage onward cellular activity is asynchronous. Part of the cells already show the signs of involution, while others histolyse only after the activation phase subsequent to moulting. PGL in G. mellonella is one of the larval tissues. In the course of activation its ultrastructure changes as a function of juvenile hormone (JH) cocentration, in the absence of which it histolyses. Accordingly, it has seemed to us to be a suitable model for the cytological study of JH activity.
