| Abstract | We have mapped the DNA sequences bound to the nuclear scaffold along 320,000 base-pairs of a genetically well-defined region of the Drosophila chromosome. We have found that the domains delimited by the scaffold attachment regions are heterogeneous in size (ranging from 26,000 to 112,000 base-pairs in this interval), and that the attachment sites are within unique sequences as judged by blot hybridization. We also found that looped domains contain up to five, or even eight, unrelated genes including, in some cases, more than one transcribed gene. The loop organization unravelled here in cultured cells does not correspond to the banding pattern seen in salivary gland polytene chromosomes. | |
