Fig. 6. Viability of cells containing either an inverted or a direct repeat dicentric chromosome is inhibited by low concentrations of benomyl. Strains containing either inverted or direct repeat dicentric constructs were grown in galactose media, washed and plated on solid media containing either galactose or glucose and the indicated concentrations of benomyl. The proportion of viable cells was determined by dividing the number of colonies that grew on glucose media by those on galactose. Shown are mean values for the results of three independent experiments, normalized to a control viability of 100%.
