Interactions between the lysine-rich histone F1 and deoxyribonucleic acid.


1. The interactions of the lysine-rich histone F1 with DNA have been studied at various histone to DNA ratios, in water and in the presence of uni- and bi-valent cations. In water only, histone F1, even in fourfold excess, is unable to precipitate all the DNA. In 0.14m-sodium chloride, 0.8mg. of histone F1 is required to precipitate 1mg. of DNA, whereas in… (More)
