Methods for producing a paired tag from a nucleic acid sequence are provided in which the paired tag comprises the 5' end tag and 3&#x2032; end tag of the nucleic acid sequence. In one embodiment, the nucleic acid sequence comprises two restriction endonuclease recognition sites specific for a restriction endonuclease that cleaves the nucleic acid sequence distally to the restriction endonuclease recognition sites. In another embodiment, the nucleic acid sequence further comprises restriction endonuclease recognition sites specific for a rare cutting restriction endonuclease. Methods of using paired tags are also provided. In one embodiment, paired tags are used to characterize a nucleic acid sequence. In a particular embodiment, the nucleic acid sequence is a genome. In one embodiment, the characterization of a nucleic acid sequence is karyotyping. Alternatively, in another embodiment, the characterization of a nucleic acid sequence is mapping of the sequence. In a further embodiment, a method is provided for identifying nucleic acid sequences that encode at least two interacting proteins.
