Fragments of Euglena chloroplast DNA generated by endonuclease R-Eco RI were separated by agarose-gel electrophoresis into 24 distinct bands. At least five fragments contain sequences complementary to chloroplast ribosomal RNA, Most of the Eco RI fragments have been cloned in a plasmid of Escherichia coli. Three of the cloned fragments were shown to contain chloroplast ribosomal RNA sequences by DNA-RNA hybridization.
由核酸内切酶R-Eco RI产生的眼虫叶绿体DNA片段，通过琼脂糖凝胶电泳被分离成24条不同的条带。至少有五个片段含有与叶绿体核糖体RNA互补的序列。大多数Eco RI片段已被克隆到大肠杆菌的质粒中。通过DNA-RNA杂交显示，其中三个克隆片段含有叶绿体核糖体RNA序列。
