The nucleotide sequences of 4.5S RNAs associated with poly-(A)-containing RNAs of mouse and hamster cells were determined. These RNAs have 91 to 94 nucleotides, a high content of G (almost 40%) and no modified nucleoside. The 5'-termini are pppG, but the 3'-termini lack uniformity in the number of uridylate residues. These molecules contain two sets of repeating sequences, and a central purine-rich sequence. There is only one base exchange between mouse and hamster 4.5S RNAs. Possible binding sites of these RNAs to poly(A)-containing RNAs are discussed.
测定了与小鼠和仓鼠细胞中含多聚腺苷酸（poly - (A)）的RNA相关的4.5S RNA的核苷酸序列。这些RNA含有91至94个核苷酸，鸟嘌呤（G）含量高（几乎40%）且无修饰核苷。5′端为三磷酸鸟苷（pppG），但3′端尿苷酸残基数量缺乏一致性。这些分子包含两组重复序列和一个富含嘌呤的中央序列。小鼠和仓鼠的4.5S RNA之间只有一个碱基交换。讨论了这些RNA与含poly(A)的RNA可能的结合位点。
