Abstract
Escherichia coli nucleoids were visualized in a compact, highly supercoiled conformation at 1 M NaCl. After the salt concentration was lowered to 0.15 M NaCl, the nucleoids uncoiled in beaded fibers in which RNA-mediated structural domains could be distinguished.
摘要
在1M氯化钠条件下，大肠杆菌类核呈现为紧密、高度超螺旋的构象。当盐浓度降至0.15M氯化钠时，类核解旋成串珠状纤维，其中RNA介导的结构域可以被区分出来。
