Nuclear matrix - Wikipedia
网页In biology, the nuclear matrix is the network of fibres found throughout the inside of a cell nucleus after a specific method of chemical extraction. According to some it is somewhat analogous to the cell cytoskeleton.
Nuclear matrix - Definition and Examples - Biology Online
网页2021年3月1日 · The nuclear matrix is the network of fibers in the nucleus as cytoskeleton is to the cell although nuclear matrix is more dynamic. Thus, similar to cytoskeleton, the nuclear matrix largely provides mechanical support.
Nuclear structure - Wikipedia
网页The liquid drop model is one of the first models of nuclear structure, proposed by Carl Friedrich von Weizsäcker in 1935. [5] It describes the nucleus as a semiclassical fluid made up of neutrons and protons, with an internal repulsive electrostatic force proportional to the number of protons.
Half a Century of “The Nuclear Matrix” - Molecular Biology of the …
网页2017年10月13日 · A cell fraction that would today be termed “the nuclear matrix” was first described and patented in 1948 by Russian investigators. In 1974 this fraction was rediscovered and promoted as a fundamental organizing principle of …
Nuclear Matrix - an overview | ScienceDirect Topics
网页The nuclear matrix may be defined as a residual nuclear scaffolding system with dynamic properties that provides functional organization for the DNA. The nuclear matrix may provide a direct passageway from the interior of the nucleus to the pore complexes.
Nucleus: Structure and Functions • Microbe Online
网页A network of thin, crisscrossed, protein-containing fibrils connected end to end with the nuclear envelope is called a nuclear matrix. It acts as a nuclear skeleton and remains intact when DNA and chromatin get removed.
Nuclear matrix - structure, function and pathogenesis
网页2016年12月20日 · 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.
Nuclear Matrix - an overview | ScienceDirect Topics
网页The nuclear matrix is the salt-extracted structure of the nucleus and consists of approximately 10% of the nuclear proteins and is virtually devoid of lipids, DNA, and histones. The nuclear matrix also plays a central role in RNA processing. Newly synthesized heteronuclear RNA and small nuclear RNA are enriched on the nuclear matrix.
The Nuclear Matrix: Structure, Function and DNA Replication
网页1992年1月1日 · This chapter discusses the structure, function, and DNA replication of the nuclear matrix. Standard thin sectioning and heavy metal staining reveals several major components in the cell nucleus: deeply stained, transcriptionally inactive heterochromatin, the nucleolus, a surrounding double-membraned nuclear envelope inundated with …
The nuclear matrix: Three-dimensional architecture and protein ...
网页The matrix is bounded by an outer nuclear lamina connected to the cytoskeletal framework, as well as the inner filaments. The filaments range in diameter from 3 to 22 nm, and are organized in a three-dimensional anastomosing network in which nucleoli are enmeshed.
