Abstract

The nucleotide sequences of 5S rRNAs from three ciliated protozoa, Paramecium tetraurelia, Tetrahymena thermophila and Blepharisma japonicum have been determined. All of them are 120 nucleotides long and the sequence of probable tRNA binding site of position 41-44 is GAAC which is characteristic of the plant 5S rRNAs. The sequence similarity percents are 87% (Paramecium/Tetrahymena), 86% (Paramecium/Blepharisma) and 79% (Tetrahymena/Blepharisma), suggesting a close relationship of these three ciliates.

摘要

已测定了三种纤毛原生动物——四膜虫、嗜热栖热四膜虫和日本睫毛虫5S rRNA的核苷酸序列。它们均为120个核苷酸长,41 - 44位可能的tRNA结合位点序列为GAAC,这是植物5S rRNA的特征。序列相似百分比分别为87%(四膜虫/嗜热栖热四膜虫)、86%(四膜虫/日本睫毛虫)和79%(嗜热栖热四膜虫/日本睫毛虫),表明这三种纤毛虫关系密切。
