An approach to the study of the properties of genetic texts is propose
d. It is based on the investigation of the frequencies of all possible
words (subsequences) in a text. The most important effect is that the
original text could be reconstructed completly without deletions and/
or mistakes using the set of words which are met in the text as a sing
le copy. The length of words for which the effect occurs is a measure
of the text redundancy. Some real genetic sequences were studied as we
