Abstract
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.
摘要
已根据复性动力学数据计算出草履虫的μ和π共生体的分子大小。μ颗粒DNA的观测值为0.78×10⁹道尔顿，π颗粒DNA的观测值为0.81×10⁹道尔顿。分析复杂度的估计值分别为4.45×10⁹和5.05×10⁹道尔顿。基于这些数据，μ和π共生体似乎拥有多个基因组，且每个DNA序列至少包含5或6个拷贝。
