Методом Монте-Карло розраховано залежність ймовірності утворення вузлів при випадковій циклізації молекули ДНК, дисперсії райзингу і коефіцієнта набухання кільцевих ДНК від ефективного діаметра молекули. Дуже різкий характер цих залежностей відкриває шлях для надійного експериментального визначення ефективного діаметра ДНК як функції іонної сили розчину.
