2 cze 2024 · Nucleoplasm is a type of protoplasm that is present in the nucleus. Protoplasm is the liquid (composed of water, and dissolved molecules) inside the cell. The liquid inside the nucleus has a different composition than the rest of the cell.
The nucleoplasm resembles the cytoplasm of a eukaryotic cell in that it is a gel-like substance found within a membrane, although the nucleoplasm only fills out the space in the nucleus and has its own unique functions.
The nucleoplasm is the contents of the cell nucleus other than the nucleolus and chromatin and consisting of interchromatin and perichromatin granules, ribonucleoproteins, and the nuclear matrix (Dorland, 2011).
The main function of the nucleoplasm is to serve as a suspension substance for the organelles inside the nucleus. It also helps maintain the shape and structure of the nucleus, and plays an important role in the transportation of materials that are vital to cell metabolism and function.
Cell nucleus is an organelle bounded by a double membrane, which undergoes drastic reorganization during major cellular events such as cell division and apoptosis. Nucleophagy (macroautophagy) is involved in the elimination of whole nuclei, micronuclei, or chromatin; for additional information related to chromatin elimination, see Chromatophagy ...
Inside the nuclear membrane is the nucleoplasm, which main function is to store DNA and enanble DNA-dependent processes such as transcription to occur in a controlled environment. The nucleoplasm contains several non-membrane bound substructures, such as nuclear bodies and nuclear speckles.
