It focuses especially on the 40s and the beginning of the 50s. Scientific papers from that period were the main source of information. The author tried to capture not only generally accepted notions about genes and genic action but also those that had not pushed through in those days, nevertheless, that had offered a non- standard point of view which could have later become inspirative for molecular genetics. The work documents searching for links between genes and enzymes or ideas of potential divisibility of the gene. The dissertation assigns a very important role to those phenomena that emphasized the significance of the gene order or the order of genic parts. In Goldschmidt's interpretation of pseudoallelism the author sees the thought that the essence of a gene is its position and considers this the beginnings of "digital" thinking about the gene. The dissertation pays attention to "analogue" thinking about the gene, as well. This thinking took account of molecular shaping and represented a blind alley for the early molecular genetics. The work confirms to a certain extent the Kuhnian vision of the development of scientific disciplines. It finds the...
