Abstract <p>As is known, almost all hereditary information about the innumerable characteristics of a multicellular organism, including the human body, is encoded in a certain way in the nucleus of a fertilized egg. The principles of the unfolding of genetic information in the development of a multicellular embryo have long attracted the attention of both biologists and representatives of various other sciences. While molecular biologists concentrate on the informational and cybernetic aspects of the storage and transmission of genetic information, the authors of biosemiotic studies insist on the specificity of biological signs in these processes and on the special nature of biological texts. We focused on the information aspects of these processes, and, to demonstrate the analogies between them and with linguosemiotic concepts, we describe the problems of complexity and hierarchy of genetic mechanisms for the implementation of genetic information in embryogenesis, as it is seen in systems biology.</p>
