The Cell Nucleus, Volume IX: Nuclear Particles, Part B discusses "splicing", "processing", and the controls of transcriptional and transport events which must be essential to cells that are either growing or are phenotypically differentiated. The book describes the characteristics and structure of nuclear 30 S RNP particles; as well as the composition and general topology of RNA and protein in monomer 40 S ribonucleoprotein particles. The text also demonstrates the two-dimensional gel electrophoresis of nuclear particles and immunocytochemistry of nuclear hnRNP complexes; the enzymatic activities associated with hnRNP; and the digestion products of nuclear ribonucleoprotein. The nucleocytoplasmic transport of mRNA; the nucleocytoplasmic transport of ribosomal subparticles; and the rnp particles involved in release of in vitro synthesized poly(a)-containing RNA in isolated nuclei are also considered. The book further tackles nuclear bodies as functional indicators in the target cells of sex steroid hormone; and the functional implications of nuclear glycoproteins and glycosaminoglycans. Cell biologists, geneticists, pharmacologists, molecular biologists, biochemists, and students taking related courses will find the book invaluable.
