Excerpt
X-ray diffraction techniques have been used to study nucleohistone (DNH) in a variety of experimental conditions (Luzzati and Nicolaieff, 1959, 1963; Wilkins et al., 1959; Bram and Ris, 1971). Although the results from the various studies have largely been in agreement, a series of models have been suggested to explain them. At this point in time, the available X-ray diffraction data lacks sufficient detail to enable a rigorous structure determination to be contemplated.
The various groups of workers involved in studying nucleohistone by diffraction techniques can conveniently be divided according to their lines of research: those who have studied unoriented solution and gel specimens (Luzzati and Nicolaieff, 1959, 1963; Bram and Ris, 1971), and those who, have drawn fibers from nucleohistone gels, thereby inducing molecular orientation (Wilkins et al., 1959; Pardon et al., 1967). The former group have considered both the presence of a continuous scatter profile and also the...
