Abstract
The nucleotide sequence of Pinus silvestyris 5S rRNA was determined using two independent methods and compared with other plant 5S rRNAs. It shows more than 90% sequence homology with gymnosperm 5S RNAs. The free energy (delta G) analysis of 5S rRNAs from gymnosperms, angiosperms and the other higher plants revealed that the free energy of this ribosomal RNA decreases with evolution.
摘要
利用两种独立方法测定了欧洲赤松5S rRNA的核苷酸序列，并与其他植物5S rRNAs进行了比较。它与裸子植物5S RNAs的序列同源性超过90%。对裸子植物、被子植物及其他高等植物5S rRNAs的自由能（ΔG）分析表明，这种核糖体RNA的自由能随进化而降低。
