摘要: Rat liver 60S ribosomal subunits were irradiated with 254-nm ultraviolet light (1.26 X 10(4) quanta/subunit), under conditions which preserved their functional activity. Cross-linked RNA-protein complexes recovered after unreacted proteins had been removed by repeated acetic acid extractions. Proteins linked to the whole rRNA, 5S RNA and 28-5.8 S RNAs identified two-dimensional gel electrophoresis hydrolysis ribonucleases T1 A. Our results showed that numerous interact rRNAs (at least ten RNA, eight among these three are common both) have discussed in of all available data.
