of the nucleus within the cell. Due to the central vacuole in a plant cell, the nucleus is usually not located in the center of the cell; rather, it is usually crowded nearer the plasma membrane. In most animal cells, however, the nucleus is located in the center of the cell, as this position is ideal in the process of mitosis, and there is no large central vacuole located in animal cells.
The nucleus contains the genes which control the entire cell, and, within the eukaryotic division of cells is uniform among all cells, that is, every eukaryotic cell has a nucleus which functions in the exact manner as other eukaryotic nuclei.
The nucleus of a eukaryotic cell performs three primary functions; these three functions make it possible for the cell to function, and to exist, as the building block of organisms. The Nucleus contains the genetic information of a cell. Encoded in this genetic information, deoxyribonucleic acid (DNA), are the instructions for all structures and ...

membrane that bounds the cell. The phospholipid bilayer is visually represented in figure C. This semi-permeable membrane allows for the transport of necessary materials in to the nucleus as well as the export of materials such as mRNA. The nuclear envelope is actually made up of two nuclear membranes, separated by a space of about 20-30 nm.

Nuclear pores

Pore complexes cover the surface of the nuclear envelope; these pores assist in the transport of large molecules in to and out of the nucleus. Nuclear pores are each bordered by a ring of eight protein particles.
Nucleolus
The nucleolus is the most visible structure within the nucleus, during interphase. The nucleoli function ...
