abstract：:Electrophoresis of the mixture of proteins from purified snRNPs U1, U2, U4/U6 and U5 on SDS-polyacrylamide gels that had been allowed to polymerise in the presence of high TEMED concentrations have revealed the presence of proteins in the snRNPs that previously had eluded detection. The most striking case is that of p...

abstract：:Genomes undergo changes in organization as a result of gene duplications, chromosomal rearrangements and local mutations, among other mechanisms. In contrast to prokaryotes, in which genes of a common function are often organized in operons and reside contiguously along the genome, most eukaryotes show much weaker clu...
