A method of producing a genetically engineered organism, by (a) incorporating into said organism a functional DNA sequence and (b) incorporating into said organism a non-functional DNA sequence, wherein said non-functional DNA sequence corresponds to the results of the application of a predefined coding scheme to an information message, said information message is related to said functional DNA sequence, said predefined coding scheme provides a mapping from a plurality of possible information messages into a plurality of DNA sequences. Said functional and said non-functional DNA sequence remain linked during reproduction of the organism for a practically relevant period of time.
