  摘要：Chemical short-range ordering is expected to be a key factor for tuning the electronic structure of semiconductors. However, experimental evidence of short-range ordering is still lacking due to the challenge of characterizing atomic-scale ordering motifs. Here, we determined the presence of short-range order in a ternary GeSiSn semiconductor system using advanced energy-filtered four-dimensional scanning transmission electron microscopy and large-scale atomistic models generated by a machine ...

  摘要：Distinguishing functional splice sites from abundant cryptic sites in precursor messenger RNAs (pre-mRNAs) represents a fundamental challenge in decoding mammalian genomes. We demonstrate that the specific RNA polymerase II (Pol II) subunit RPB9 directly interacts with the 3 ' AG dinucleotide binding factor U2AF1 to initiate 3 ' splice site recognition. Combined with recent structural insights into Pol II-mediated 5 ' splice site selection, these findings support a cotranscriptional mechanism ...
