Abstract
Two kinds of nuclear membranes are described. One (of gland cells) has the high resistance of 1.5 [OMEGA] cm2 and sustains a resting potential of about 13 mv between nucleoplasm (negative) and cytoplasm. Another one (of oocytes) has a resistance indistinguishable from nucleoplasm and cytoplasm and no resting potential. The former kind of nuclear membrane is a formidable diffusion barrier even for particles of ion size; the latter is more permeable.Keywords
