what structure separates the contents of the nucleus cytoplasm?
karyosome
bullet::::- in eukaryotic cells, the nuclear membrane separates the contents of the nucleus from the cytoplasm of the cell. the nuclear membrane is formed by an inner and outer membrane, providing the strict regulation of materials in to and out of the nucleus. materials move between the cytosol and the nucleus through nuclear pores in the nuclear membrane. if a cell’s nucleus is more active in transcription, its membrane will have more pores. the protein composition of the nucleus can vary greatly from the cytosol as many proteins are unable to cross through pores via diffusion. within the nuclear membrane, the inner and outer membranes vary in protein composition, and only the outer membrane is continuous with the endoplasmic reticulum (er) membrane. like the er, the outer membrane also possesses ribosomes responsible for producing and transporting proteins into the space between the two membranes. the nuclear membrane disassembles during the early stages of mitosis and reassembles in later stages of mitosis.
