In chromatin from the sperm of two Bivalvia molluscs a highly basic low molecular mass sperm‐specific protein (S‐protein) has been found in addition to the full complement of histones. It is shown that sperm chromatin preserves nucleosomal organization, some parameters of which are specific: (i) DNase I cuts DNA within the sperm nuclei with dinucleosomal periodicity; (ii) linker DNA of the nucleosome is significantly elongated. The S‐protein is shown to be located on the linker DNA.
