Although interphase chromatin appears to be uniformly distributed, the chromosomes are actually arranged in an organized fashion and divided into discrete functional domains that play an important role in regulating gene expression.
What is periphery of nucleus?
A hallmark of the skeletal muscle cell is the position of nuclei at the periphery. After spreading, nuclei migrate from a central position within the myotube to the periphery. In the mammalian system, nuclear migration to the periphery occurs after the formation of myofibrils, the contractile fibers filling the cell.
What is the main function of nucleus?
The nucleus is the largest, most prominent organelle inside the cell. The functions of the nucleus are that it houses genetic material (DNA). it is the site of RNA production and it helps regulate cell metabolism by generating various enzymes.
What is nucleus and its function?
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.
Why do muscle have nuclei?
“To build muscle mass you need to make more of the contractile proteins that create that force,” says Kristian Gundersen, a muscle biologist from the University of Oslo. Nuclei power the building of more muscle, making them “a bit like factories,” says Gundersen. The more nuclei, the bigger and stronger the muscle.
