Abstract

In the course of the experiments described above it became clear that the two mutations used were not identical. The mutation was isolated by Tully (1976) as conferring resistance to chromate, the mutation arose spontaneously and simultaneously with a mutation, (it may be the result of an inversion with ends in these two genes). The mapping of the genes (see above, Table 3) shows that and lie on opposite sides of We therefore investigated the biochemical nature of the mutations.
