Nucleus (Cell Nucleus)

Nucleus (Cell Nucleus)
Is the most important for the cell, 5 µm in diameter, encircled by a double membrane (outer and inner membrane) separated by a room of about 20-40 nm. The membrane core is composed oflipids and proteins. Around the core there are pores diameter 100 nm to set keluar-masuknyamacromolecules and nucleus. On the lips of pori, the inner membrane and the outer membraneseem fused. Within the nucleus there are nukleoplasma (the core plasma), the son of inti(nucleolus), and genetic material in the form of the thread-the thread as the cell. When the cellwill divide, thread-thread cell retracts and thicken, then called chromosomes. Nukleous (core)ball-shaped, thick, colored and attached to the cell. The number of nukleous vary, can beberjumpah two or more, and it serves to synthesize components of Ribosomes.
