Abstract
Analysis of the polarization of fluorescence from Drosophila virilis polytene chromosomes stained with acridine orange suggests that the DNA in the interband regions of these chromosomes cannot be in a supercoiled configuration, but must lie parallel to the chromosome axis.
摘要
对用吖啶橙染色的果蝇多线染色体的荧光偏振分析表明，这些染色体间带区域的DNA不可能处于超螺旋构型，而必定与染色体轴平行排列。
