    Abstract

    Fusion of symmetry and asymmetry can be observed in biological molecules and cells. For example, the frequencies of purines and pyrimidines in double-strand DNA in a symmetric ratio of 1:1, while the asymmetric density ratios of purines and pyrimidines in RNA are between 1:1 and approximately 2:3.Size ratios of cells are also in the symbiotic fusion of symmetry and asymmetry. The cyto-fluid dynamic theory and onto-biology reported previously (Naitoh, 2001 & 2008) clarify the physics on the inevitability of symmetry and asymmetry underlying life. An important point is relatively inner cells among a colony divide into asymmetric ones, while outer cells on the colony surface proliferate symmetrically with an identical size. In this report, we examined the concept of inner-asymmetry and outer-symmetry by experiments.
