Studies on the Structure and Function of Amphioxus Ribosomes Ⅰ.Isolation of Amphioxus tRNAs and 5S RNAs

  • This article reports the method for preparing Trna and 5S RNA from amphioxus (Branchiostoma belcheri Gray).Whole tissues of frozen amphioxus were homogenized in buffer Ⅰ with a Waring blendor at 0 ℃ for 30s,then the lowmolecular-weight RNAs were extracted by the phenol method.By means of column chromatography of DEAE-celloluse,DEAE-Sephadex A-50 and Sephadex G-100,tRNAs and 5S RNAs were obtained separately.They were further purified by electrophoresis on polyacrylamide gel.The accepting activity of amphioxus tRNA was determined:glycine,6.3%,alanine,5.2% and tyrosine,21%-25%.
