Abstract
In concentrated solutions [calf thymus] DNA organizes spontaneously to form the cholesteric phase which is 1 type of liquid crystal. Both continuous cholesteric phases and isolated cholesteric globules in equilibrium with the isotropic phase were reproducibly obtained. A comparison is made between this in vitro cholesteric organization and dinoflagellate [Prorocentrum micans] chromosomes which present the same organization in vivo. The observed defects are analyzed in the 2 cass. The cholesteric organization is probably due to self-assembly phenomena and the shape of globules and chromosomes is due both to surface tensions and to the presence of defects.This publication has 8 references indexed in Scilit:
