IN The present invention relates to a method for the recombinant production of DNA single stranded molecules, comprising the steps of (1) providing a pseudogene nucleic acid; (2) integrating the pseudogene nucleic acid into a vector, transforming bacterial cells with said vector and producing a precursor ssDNA from said vector under bacterial culture conditions; (3) isolating the precursor ssDNA from the bacterial culture; (4) digesting the precursor ss DNA under reaction conditions where self-cleaving DNA sequences become active; and (5) separating and obtaining the target single stranded DNA oligo- or polynucleotide(s). The method of the present invention is suitable for the mass production of DNA single stranded molecules. The present invention further relates to the use of the target single stranded DNA oligo- or polynucleotide(s), in particular in DNA nanotechnology, or as research tools.
