Suboptimal condition of alkaline denaturation was used to partially denature Haemophilus influenzae DNA and fractions from these DNA molecules possessing various degrees of strandedness were resolved by hydroxyapatite column chromatography. Exonuclease I sensitivity as well as transforming activity were used to elucidate the secondary structure of these fractions. Fractions supposedly corresponding to the single- and double-stranded DNA were shown to be different from the completely denatured and native DNA, respectively.
