2019年5月17日 · Research on the detection of tRNA and ribosomal (rRNA) modifications is a more mature field than that dealing with mRNAs. After all, these noncoding RNAs are more abundant than mRNA, facilitating biochemical studies.
RNA Structure: Reading the Ribosome | Science - AAAS
2005年9月2日 · The hundreds of individual rRNA helices in the ribosome allow us to draw new generalities about RNA secondary structure. Most rRNA helices terminate at both ends in G-C pairs. As predicted from sequence analysis and chemical probing studies, noncanonical A-G pairs often flank the ends of helices (38, 39).
