Abstract
We have cloned and determined the nucleotide sequence of 18 DNA fragments hybridizing to 5S rRNA from two Aspergillus species--A. wentii and A. awamori. Four of the analyzed sequences were pseudogenes. The gene sequences of these two species were very similar and differed from Aspergillus nidulans at both constant and microheterogeneous sites.
摘要
我们已经克隆并测定了来自两种曲霉属真菌——文氏曲霉和泡盛曲霉的18个与5S rRNA杂交的DNA片段的核苷酸序列。分析的序列中有4个是假基因。这两个物种的基因序列非常相似，并且在恒定位点和微异质位点上都与构巢曲霉不同。
