За допомогою двовимірного електрофорезу виявлено структурний перехід нового типу в гомопурин-гомопіримідиновій ділянці в надспіральній ДНК. На відміну від інших досліджених переходів, цей перехід сильно залежить від рН, що проявляється у зменшенні щільності негативної надспіралізаціі, необхідної для структурної зміни, при зниженні рН. Нова структура ДНК названа Н-формою.Посилання
