The molecular size of mu and pi symbionts of Parameciumaurelia has been calculated from renaturation kinetic data. Observed values were 0.78 x 10(9) daltons for mu particle DNA and 0.81 x 10(9) daltons for pi particle DNA. Estimates of analytical complexity were 4.45 x 10(9) and 5.05 x 10(9) 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.
