Nucleic acids are compacted, substantially without aggregation, to facilitate their uptake by target cells of an organism to which the compacted material is administered. The nucleic acids may achieve a clinical effect as a result of gene expression, hybridization to endogenous nucleic acids whose expression is undesired, or site-specific integration so that a target gene is replaced, modified or deleted. The targeting may be enhanced by means of a target cell-binding moiety. The nucleic acid is preferably compacted to a condensed state.

[ We claim:] [1.] A method of achieving expression of a protein in a subject comprising:administering to a subject a composition comprising unaggregated nucleic acid complexes, each complex consisting essentially of a single nucleic acid molecule encoding a protein and one or more carrier molecules,

[ We claim:] [1.] A method of achieving expression of a protein in a subject comprising:administering to a subject a composition comprising unaggregated nucleic acid complexes, each complex consisting essentially of a single nucleic acid molecule encoding a protein and one or more carrier molecules, said carrier molecule having a nucleic acid binding moiety through which it is complexed to the nucleic acid wherein said complex is compacted to a diameter which is less than (a) double the theoretical minimum diameter of a complex of said single nucleic acid molecule and a sufficient number of carrier molecules to provide a charge ratio of 1:1, in the form of a condensed sphere, or (b) 30 nm, whichever is larger, whereby said protein is expressed in the subject.
