WebA team led by Prof. ZHANG Kaiming from the University of Science and Technology (USTC) solved six conformations in the second-step self-splicing of Tetrahymena ribozyme using cryogenic electron microscopy (cryo-EM), revealing the mechanism of group 1 introns coordinating self-splicing reactions. Their work was published inNature … WebApr 12, 2024 · A region of eukaryotic DNA that is transcribed into RNA may contain any number of exons and introns. The sections that are retained in the mature RNA molecule after RNA splicing are termed exons, with the regions that are removed referred to as introns (Figure 1 A). 1 The term exon refers to these regions in both DNA and RNA …
