RESUMO
Experiments are described that characterize the organization of DNA sequences in the water mold Achlya bisexualis. These experiments demonstrate that repetitive and single copy sequences in the Achlya genome are arranged in a long-period interspersion pattern. Estimates of the spacing intervals between repetitive and single copy DNA indicate, however, that the interspersion pattern in Achlya is longer than has been previously reported in other eukaryotes. These data and measurements of structural gene expression in Achlya [Timberlake, W.E., Shumard, D. S. & Goldberg, R. B. (1977) Cell 10, 623-632] make it difficult to propose a regulatory function for repeated DNA in this eukaryote.
