Nicotiana tabacum chloroplast DNA contains two copies each of 16S and 23S rRNA genes. These genes are located in an inverted order as determined from restriction fragment mapping and Southern hybridization to restriction fragments. The position of these genes on the N. tabacum chloroplast DNA molecule has been established relative to a complete map of SalI and SMaI restriction enzyme cleavage sites.
烟草叶绿体DNA含有16S和23S rRNA基因的两个拷贝。根据限制片段图谱和与限制片段的Southern杂交确定,这些基因以反向顺序排列。相对于SalI和SmaI限制酶切割位点的完整图谱,已确定了这些基因在烟草叶绿体DNA分子上的位置。
