Perturbance analysis of nuclear determination in Tetrahymena I: background, rationale, and illustrative example, employing temperature responses.
A model based on comparative considerations, is presented for the nuclear determination of mating type in Tetrahymena thermophila. The model proposes a system of three binary control elements, each capable of stable persistence in one of two states. A general method is proposed for evaluating the model and for assigning particular mating types to particular compound states. Preliminary assignments of mating types are made from the responses of nuclei to temperature differentials.
