Abstract: DNA molecules can be condensed into nanometer-like condensation compounds under the effect of multivalent cations/polyvalent positive ions,including positive ion polymers,proteins,inorganic ions of high wtlence,etc.Condensation is aroused by 67～90% of neutralized negative charge of DNA phosphate base,whose process is accompanied by aggregation process of micrones.Common condensation compounds appear hooped,with the size of 50～300nm.Condensation is mainly affected by positive charge of condensation agent,whose structure as well as the size of DNA molecules and base component also influences the process of condensation.
