Summary

A large number of cytochemical staining techniques together with chemical and enzymic extractions have been used on Prorocentrum micans. The object of this study being to ascertain the main chemical components of the unusual chromosomes found in the Dinophyceae.

DNA was the only major component which could be positively determined and unlike most other chromosomes these appeared to contain no protein or RNA. However, the chromosomes were embedded in a granular proteinaceous “nuclear matrix,” the function of which is as yet unknown. The similarity in the composition and structure of the chromosomes of Prorocentrum and the nuclei of Bacteria are discussed.
