| Abstract: | The molecular size of mu and pi symbionts of Parameciumaurelia has been calculated from renaturation kinetic data. Observed values were 0.78 × 109 daltons for mu particle DNA and 0.81 × 109 daltons for pi particle DNA. Estimates of analytical complexity were 4.45 × 109 and 5.05 × 109 daltons respectively. Based on these data, mu and pi symbionts appear to possess multiple genomes and contain a minimum of 5 or 6 copies of each DNA sequence. |
