Abstract:Biochemical properties of DNA preparations obtained from light-anaerobicallygrowth R. spheroides cells and from dark-aerobically grown cellswere examined comparatively using methylated albumin kieselguhrcolumn chromatography. The DNA preparation from light-growncells, which formed chromatophores, exhibited considerable heterogeneityin its size or conformation. 1 Present address: The Third Department of Medicine, TohokuUniversity School of Medicine, Sendai, Japan.
