This Week in Science

In Science this week, a team led by investigators at the University of Massachusetts Medical School reports its use of yeast genetic engineering, chemical biology techniques, and multi-wavelength fluorescence microscopy to "follow assembly of single spliceosomes in real time in whole-cell extracts." In its investigations, the team found that spliceosomal subcomplexes sequentially associate with pre-mRNA, such that they produce functional spliceosomes and that each subcomplex is reversible.
