Abstract
A method for producing a composition including a nucleic-acid-containing complex is characterized in that two single strand nucleic acid polymers which can at least partly form double strands are separately mixed, in a single strand form, with a cationic carrier or with source materials for the cationic carrier before the cationic carrier is formed. The resulting mixture is then dispersed in water during the production process of the nucleic-acid-containing complex.
