Comments "Because the 237-bp nucleosome repeat length is typical of sea urchin sperm (primary source), [researchers] investigated whether reconstitution with the sea urchin specific linker histone H1, which is larger than the H5 used here, would affect the dimensions of the resulting folded 30-nm chromatin fiber."
