Description:
One of the rewards of having a Drosophila melanogaster whole-genome sequence will be the potential to understand the molecular bases for structural features of chromosomes that have been a long-standing puzzle. Analysis of 2.6 megabases of sequence from the tip of the X chromosome of Drosophila identifies 273 genes. Cloned DNAs from the characteristic bulbous structure at the tip of the X chromosome in the region of the broad complex display an unusual pattern of in situ hybridization. Sequence analysis revealed that this region comprises 154 kilobases of DNA flanked by 1.2-kilobases of inverted repeats, each composed of a 350-base pair satellite related element. Thus, some aspects of chromosome structure appear to be revealed directly within the DNA sequence itself.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benos, P V -- Gatt, M K -- Ashburner, M -- Murphy, L -- Harris, D -- Barrell, B -- Ferraz, C -- Vidal, S -- Brun, C -- Demailles, J -- Cadieu, E -- Dreano, S -- Gloux, S -- Lelaure, V -- Mottier, S -- Galibert, F -- Borkova, D -- Minana, B -- Kafatos, F C -- Louis, C -- Siden-Kiamos, I -- Bolshakov, S -- Papagiannakis, G -- Spanos, L -- Cox, S -- Madueno, E -- de Pablos, B -- Modolell, J -- Peter, A -- Schottler, P -- Werner, M -- Mourkioti, F -- Beinert, N -- Dowe, G -- Schafer, U -- Jackle, H -- Bucheton, A -- Callister, D M -- Campbell, L A -- Darlamitsou, A -- Henderson, N S -- McMillan, P J -- Salles, C -- Tait, E A -- Valenti, P -- Saunder, R D -- Glover, D M -- New York, N.Y. -- Science. 2000 Mar 24;287(5461):2220-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The European Bioinformatics Institute, Wellcome Trust Genome Campus, Hinxton Hall, Cambridge CB10 1SD, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10731137" target="_blank"〉PubMed〈/a〉
