A study of DNA from chloroplasts separated by counter-current distribution.
Three types of chloroplasts (Peak I, Peak II, and Peak III chloroplasts) isolated by counter-current distribution in aqueous polymer two-phase systems have been studied with respect to DNA content. (The characterization was performed by studying the buoyant density, the melting profile and the amount of DNA of each type). The DNA was found to differ between the three types of chloroplasts.
