  9. Arginine rich human histone h3 is a kind of basic nucleosome protein. in the medium of physiological condition, by electrostatic interaction, histone h3 which arginine impart to it a positive charge binds to dna which phosphate groups impart to it a negative charge. in this paper, in order to establish a new technology of transfection, the functional domains la and ii gene segments of pea were lined with histone h3 gene segment, then a recombinant fusion protein was constructed which serves as c arrier for transfer of dna via receptor - mediated endocytosis
