Cytochemistry and Immunology of some Nuclear Proteins in a Primative Dinoflagellate
Dinoflagellates represent an outstanding experimental model for the study of nuclear structure-function relationships, due to the permanently condensed DNA in ‘arch-shaped’ chromosomes and the constant presence of nucleoli and nuclear membrane throughout the whole cell cycle. The fact that in the nucleoli the chromosomes remain distinct inside the Fibrillar Centers (FC), makes it easier to distinguish the proteins bound to DNA from those which are not. This allows a better interpretation of in situ labelling studies of nuclear components.
