During the four years, 1937-41 research on the characterization of Nucleic Acid entered upon its eighth decade, yet the first problem to be posed, that concerning the nature of nucleic acid, still awaits a satisfactory solution, With the exception of a few publications that escaped general notice, it has been believed universally that one type of nucleic acid, plant nucleic acid, was always to be found in the nuclei of plant cells, and that another type of nucleic acid, animal nucleic acid, was always contained in the nuclei of animal cells.

Sufficient evidence has now appeared to show that this generalization is no longer te able, feulgen, Behrens and Mahdihassan, as well as Behrens', by the use of a flotation method whereby the nuclei of cells could be freed from cytoplasmic constituents, have been able to isolate animal nucleic acid from the nuclei, and lant nucleic acid from the cytoplasm of rye embryos.
