[A hypothesis on the functional organization of the chromosomes of higher organisms].

C Speiser1.   

Abstract

In a preliminary report a new functional chromosome model is developed. Contrary to all present hypotheses this model considers not only the chromomeres but also the interchromomeres as independent genes. It is assumed that the interchromomeres are obligatory miniature-puffs, which are formed by the genes of "basic synthesis" (the synthesis which guarantees the fundamental cellular life). The genes involved in the basic synthesis are collectively defined as the "basic genome". The chromomeres developed during evolution through saltatory replication from the basic genes and contain the loci of the stage- and tissue-specific differential gene activity. All the genes of the differential synthesis are designated as the "differential genome".ZUSAMMENFASSUNG: In einer vorläufigen Mitteilung wird ein neues funktionelles Chromosomenmodell entwickelt, das entgegen allen bisherigen Hypothesen sowohl Chromomeren als auch Interchromomeren als eigenständige Gene betrachtet. Es wird angenommen, daß die Interchromomeren obligatorische Miniatur-Puffs sind, die von den Genen der jeder Zelle gleichermaßen eigenen "Basissynthese" gebildet werden. Die Summe der Gene, die an der Basissynthese beteiligt sind, wird als "Basisgenom" definiert. Die Chromomeren haben sich während der Evolution durch saltatorische Replikation aus Basisgenen entwickelt und enthalten die Loci der Stadien- und gewebespezifischen differentiellen Genaktivität. Ihre Gesamtheit wird als "Differentialgenom" definiert.Für die Anregung zu dieser Arbeit gilt Herrn Prof. Dr. F. Mechelke mein besonderer Dank.
