Specific membrane interactions such as lipid vesicle docking and fusion can be mediated by synthetic DNA-lipid conjugates as a model for the protein-driven processes that are ubiquitous in biological ...
三种壁虎染色体核仁组织者的银染色观察与蹼壁虎的核型Observation on the Ag-NORs in 3 Species of Gekko and the Karyotype of G.swinhonis
无蹼壁虎 铅山壁虎 多疣壁虎 核仁组织者 核型
2008/1/29
摘要本文以骨髓细胞为材料, 采用常规制片法和一步银染色技术,首次报道了无蹼壁虎、铅山壁虎和多疣壁虑的NORs,并用α-巯基乙醇短期培养无蹼壁虎的骨髓细胞,分析其核型。结果表明,3种壁虎都仅显示一对NORs,也未见有融合现象。其中无蹼壁虎的NORs位于第18对染色体的次缢痕区,而铅山壁虎和多疣壁虎分别位于第19对和第14对上。另外,我们从C带分析中发现,铅山壁虎和多疣壁虎的NORs位点均为结构异染色...
