Wyatt (1950) analyzed the purine and pyrimidine composition of deoxypentose nucleic acids (DNA). He developed a method for the quantitative analysis of DNA using formic acid hydrolysis and paper chromatography. The purines and pyrimidines were separated on a single paper strip and estimated by measuring their absorption peaks. The method involved hydrolyzing DNA with formic acid to release purines and pyrimidines, which were then separated and quantified. The results showed that the composition of DNA is not consistent with the tetranucleotide hypothesis, but rather indicates a complex structure. The composition of DNA is unaltered by treatment with N-sodium hydroxide, and this fractionation can be used to obtain specimens free from ribonucleic acid (RNA) for analysis. The results also showed that the composition of DNA varies between different species but not within different tissues of the same species. The content of 5-methylcytosine shows particularly characteristic variations. The study also compared the composition of DNA from different sources, including animal and plant DNA, and found that the ratios of purines and pyrimidines vary with the species source of the nucleic acid, but not with different tissues from one species. The results indicate a highly complex structure of DNA, which may have a direct relation to genetic structure. The study also showed that the composition of DNA is more similar among related than unrelated species. The results suggest that DNA composition may bear some direct relation to genetic structure. The study also showed that the composition of DNA is not consistent with any simple theory of nucleic acid composition, but indicates a highly complex structure.
