SYNOPSIS. Methods have been developed for the isolation of deoxyribonucleic acids (DNA) from Tetrahymena pyriformis, Polytomella papillata , and Aspergillus tamarii. The DNA from these organisms contained adenine (A), thymine (T), guanine (G) and cytosine (C), and the usual base‐pairing relationship, i.e., A = T; G = C was found. The ratio A + T/ G + C was 2.42, 1.42, and 1.08 for the DNA of the three organisms respectively. 5‐Methylcytosine was absent in all cases.
