The present invention relates to a novel process for the production of transgenic organisms or transgenic cells, to transgenic orgaisms or transgenic cells obtainable by the process of the present invention, to the use of vectors comprising DNA encoding a recombination promoting enzymes for curing impairments caused by environmental influences in plants or plant cells and for gene therapy in mammals or mammalian cells, and to novel vectors.

Stimulation of homologous recombination in eukaryotic organisms or cells by recombination promoting enzymes

The invention relates to a method for marking solid, liquid or gaseous substances, whereby the substance to be marked is provided with at least one synthetically produced nucleic acid sequence. Said nucleic acid sequence contains a first sequence section constructed with the 5&prime; terminal end, a second sequence comprised of at least two bases and connected to said nucleic acid sequence, and a third sequence section constructed with the 3&prime; terminal end and connected to the said nucleic acid sequence. In order to simplify the identification of the marking, the invention provides that a first primer group is used with a first primer section corresponding to the first sequence section and a second primer group is used with a third primer section corresponding to the third sequence section. Every primer group four comprises differing primer variants in at least one additional respective base which is provided on the end so that exactly one primer variant of the first primer group together with exactly one primer variant of the second primer group is complimentary to the nucleic acid sequence.
