Abstract: The invention relates to a nucleic acid which is stabilised against decomposition by exonucleases. Said nucleic acid contains the following constituents: a) a code sequence coding for a defined protein, b) optimally, a promoter sequence controlling the expression of the code sequence, and c) at least one molecule A added to an end of the linear sequence containing the constituents a and b, said molecule being linked to a non-immobilised, volumic molecule B.

Abstract: The invention relates to a method for preparative production of long nucleic acids by PCR. The method involves the following hybridization steps: a) a nucleic acid base sequence is hybridized on the 3? and 5? ends with an adapter primer; b) the product from step a) is hybridized on the 3? and 5? ends with an extension primer containing an extension sequence, wherein a nucleic acid with extension sequences amplified and enlarged in the 3? and 5? ends of the nucleic acid base sequence is then formed from the nucleic acid base sequence. The invention also relates to different applications of the inventive method.

Abstract: The invention relates to a method for producing a lysate used for cell-free protein biosynthesis, comprising the following steps: a) a genomic sequence in an organism, which codes for an essential translation product that reduces the yield of cell-free protein biosynthesis, is replaced by the foreign DNA located under a suitable regulatory element, said foreign DNA coding for the essential translation product that additionally contains a marker sequence; b) the organism cloned according to step a) is cultivated; c) the organisms from the culture obtained in step b) are lysed; and d) the essential translation product is eliminated by means of a separation process that is selective for the marker sequence. Also disclosed are said lysate and the use thereof.
