摘要: Publisher Summary This chapter describes the extracts that can be used to study assembly, structure, function, and cell cycle regulation of nuclear envelope pore complexes. The is dynamic boundary separates eukaryotic genome from cytoplasm. In addition chromosomes, all proteins enzymes needed for replication, transcription, RNA maturation are confined nucleus. Ribosomes translational factors, on other hand, restricted segregation nucleoplasmic cytoplasmic constituents established early after mitosis, when components reassemble directly onto chromosome surfaces. After chromosomes enclosed by envelope, maintained complexes in regulate movement macromolecules into out associated skeletal structures bind chromatin DNA, helps organizing structure.
