The method for marking of liquid products such as oils or oil-based products to its identity proof- and origin proof, comprises marking the product with DNA or RNA having a coding range, whose sequence is assigned to a character sequence. The character sequence is a letter- and/or a numerical sequence. The numerical sequence is a decimal number. The coding of the decimal number takes place in the sequence of the coding range. The conversion of the decimal number takes place in binary-, tertiary or quaternary number system. The method for marking of liquid products such as oils or oil-based products to its identity proof- and origin proof, comprises marking the product with DNA or RNA having a coding range, whose sequence is assigned to a character sequence. The character sequence is a letter- and/or a numerical sequence. The numerical sequence is a decimal number. The coding of the decimal number takes place in the sequence of the coding range. The conversion of the decimal number takes place in binary-, tertiary or quaternary number system. The decimal number is transformed into another number system and identical numbers of the resulting number of the other number system are assigned to a nucleotide of the nucleic acid. The coding the letters takes place that each letter is assigned to an unique triplet, quadruplet or a quintuplet by nucleotides of nucleic acid to be synthesized. A triplet is assigned to each indication of the character sequence by nucleotides within the coding range of nucleic acid. The nucleic acid has primary hybridizing places and/or spacer. The character sequence denominates the product number, the batch number, the production time and/or the production place of the product. An independent claim is included for a method for identity determination- and origin determination of marked products. Die vorliegende Erfindung betrifft im Allgemeinen das Gebiet der Produktidentifikation. Insbesondere betrifft die vorliegende Erfindung Verfahren zur Markierung von Produkten mit Nukleinsäuren, um die Identität und Herkunft der Produkte festzustellen, sie nachzuverfolgen und ihre Menge bei Verschnitt bzw. Verdünnung durch andere Produkte zu bestimmen. Weiter betrifft die vorliegende Erfindung die Verwendung von Zeichen- und Zeichenfolgen kodierenden Nukleinsäuren zur Markierung von Produkten sowie Produkte, die Nukleinsäuren umfassen, die Zeichen- und Zeichenfolgen kodieren.
