Detailed explanation-1: -Nuclear matrix is the network of fibers within the nucleus. It is the cytoskeleton of the nucleus. While the cell contains a cytoskeleton that provides structural support and a means of transport throughout the cytoplasm, the nucleus also contains fibrous scaffolding throughout in the form of nuclear matrix.
Detailed explanation-2: -The nuclear matrix (NM), or nuclear skeleton, is the non-chromatin, ribonucleoproteinaceous framework that is resistant to high ionic strength buffers, nonionic detergents, and nucleolytic enzymes.
Detailed explanation-3: -A protein found inside the nucleus of a cell. It is involved in making DNA, RNA, and proteins. It also helps control how certain genes are expressed (turned on) in a cell.
Detailed explanation-4: -It is the network of fibers found throughout the inside of a cell nucleus after a specific method of chemical extraction. The nuclear matrix contains the chromatin and nucleolus.
Detailed explanation-5: -The nuclear matrix has been defined as the dynamic structural subcomponent of the nucleus that directs the functional organization of DNA into loop domains and provides sites for the specific control of nucleic acids (Getzenberg et al., 1990; Nelson et al., 1986).
