[Theoretical model of DNA-membrane contacts].

: A DNA-membrane complex model (DMC) is presented, in which specific sites of DNA, low molecular weight RNA, and a system of two lipid (or lipoprotein) membranes take part, Morphological identity of these complexes and nuclear pores for eucaryotes and "Bayer's junctions" for procaryotes is suggested. The forces of membrane surface tension in DMC formation are analysed, and the diameter of nuclear pores is calculated.
