The deletion-fusion fragment of the Drosophila melanogaster X-chromosome deficiency Df(1)N5419 was cloned in a lambda phage vector. DNA on the genetic left side of the fusion contains sequences homologous to the roo family of transposable repetitive elements. Restriction mapping data are consistent with the right end of the roo element being situated near the breakpoint. The deficiency is of spontaneous origin, and it is possible that transposition of the roo element was involved in the deletion event.
果蝇X染色体缺失Df(1)N5419的缺失-融合片段被克隆到一个λ噬菌体载体中。融合基因左侧的DNA包含与roo家族转座重复元件同源的序列。限制性图谱数据与roo元件的右端位于断点附近一致。该缺失是自发产生的，roo元件的转座可能参与了缺失事件。
