The spectrophotometric analysis of 45S precursor rRNA shows that it contains more G and C residues than does mature 28S or 18S rRNA. The helical content and the length of double-helical segments in 45S and 28S rRNA are similar.
对45S前体rRNA的分光光度分析表明,它所含的鸟嘌呤(G)和胞嘧啶(C)残基比成熟的28S或18S rRNA更多。45S和28S rRNA中的螺旋含量和双螺旋片段长度相似。
