Abstract
The ribosomal DNA repeat unit of Aspergillus nidulans has been cloned in pBR322 and a restriction map constructed. The genes coding for the 17S, 5.8S and 25S rRNAs are found in blocks separated by a 1.7 kb spacer region, with the 5.8S RNA gene lying between the genes for the two larger RNAs. The total length of the repeat unit is 7.7 kb. The 5S rRNA is not present in the repeat unit.
摘要
构巢曲霉的核糖体DNA重复单元已被克隆到pBR322中，并构建了限制性图谱。编码17S、5.8S和25S rRNA的基因位于由1.7 kb间隔区隔开的片段中，5.8S RNA基因位于两个较大RNA基因之间。重复单元的总长度为7.7 kb。重复单元中不存在5S rRNA。
