Abstract

18S ribosomal RNA in Xenopus laevis is 1,825 nucleotides long, as inferred from sequence analysis of an 18S gene. All the 40 rRNA methyl groups can be located in the sequence. Comparison with the yeast (Saccharomyces cerevisiae) 18S sequence reveals extensive regions of high homology interspersed with tracts having little or no homology. Regions of high homology contain almost all the RNa methyl groups. Major regions of low homology area considerably richer in C + G in Xenopus than in yeast.

摘要

从非洲爪蟾18S基因的序列分析推断，其18S核糖体RNA长度为1825个核苷酸。所有40个rRNA甲基基团都可定位在该序列中。与酵母（酿酒酵母）18S序列比较发现，有广泛的高度同源区域，其间散布着很少或没有同源性的片段。高度同源区域几乎包含了所有的RNA甲基基团。非洲爪蟾中低同源性的主要区域比酵母中的C+G含量丰富得多。
