The 750 base pair tandem repeat specifying the 5S ribosomal RNA of Trypanosoma brucei brucei has been cloned and four independent clones sequenced to completion. The repeat specifies only a single 5S rRNA and is unusually long when compared with other 5S gene repeats. The sequenced copies contain a number of sequence polymorphisms similar to those seen in the ribosomal genes of other organisms. By comparison with the consensus sequence for RNA polymerase III promoters ('internal control regions') a possible 'internal control region' for RNA polymerase III can be located in the predicted position within the 5S ribosomal RNA sequence.
布氏布氏锥虫（Trypanosoma brucei brucei）中编码5S核糖体RNA的750个碱基对串联重复序列已被克隆，四个独立克隆已完成测序。该重复序列仅编码一个5S rRNA，与其他5S基因重复序列相比异常长。测序的拷贝包含许多序列多态性，类似于在其他生物体的核糖体基因中看到的那些。通过与RNA聚合酶III启动子（“内部控制区”）的共有序列比较，RNA聚合酶III的一个可能的“内部控制区”可以定位在5S核糖体RNA序列内的预测位置。
