The role of the nuclear pore complex in selective transport across the nuclear membrane has been … A nuclear pore is a channel as part of the nuclear pore complex ( NPC ), a large protein complex found in the nuclear envelope in eukaryotic cells, enveloping the cell nucleus containing DNA, which facilitates the selective membrane transport of various molecules across the membrane. Introduction. In transcription, not only the specific nucleotides, proteins, and nucleic acids must be transported into the nucleus efficiently and specifically but also the products must be exported on time. The nuclear membrane, also known as the nuclear envelope, consists of two lipid bilayers that separate the nucleoplasm from the cytoplasm. Nucleoplasm is composed of nucleolus and chromatin. Nanoscale structures are difficult to be resolved by conventional light microscopy. Nukleus biasanya terletak di tengah sel.
