nucleoplasm provides a medium by which materials, such as enzymes andnucleotides(DNA and RNA subunits), can be transported throughout the nucleus. Substances are exchanged between the cytoplasm and nucleoplasm through nuclear pores.
2. Biology The structure in the cytoplasm of a living cell that contains the cell's DNA and controls its metabolism, growth, and reproduction. A nucleus surrounded by a membrane is found in almost all the cells of eukaryotes and thus sets them apart from the cells of prokaryotes, such as...
The nucleoid, which means nucleus-like, isan irregularly shaped area containing the genetic material of the prokaryotic cell. It is different from the nucleus of a eukaryotic cell in a way that the genetic material is not enclosed in a membrane to separate it from the cytoplasm. Is a nucleus?
Figure 5-3.Diagram of nuclear pore complex that allows communication of the cell cytoplasm with the internal nuclear compartment. The diagram shows the proteins that comprise the ∼100-nm, octagon disk-shaped nuclear pore complex. The pore complex is anchored into the nuclear envelope (outer nuc...
. Type 5 (inside the nucleus) is a structure inside the nucleus (between chromosomes) (Fig.3fand Supplementary Fig.3p–s). In addition to these types, we frequently observed large GFP-LacI puncta in the cytoplasm. These puncta were found in degradative organelles, including lysosomes and ...

With this in mind, the oocyte is the recipient of choice, because it is the one cell whose cytoplasm (ooplasm) can reprogram the nucleus of cells as various as spermatozoa, T cells, B cells, and olfactory neurons to a totipotent state capable of subsequently forming a whole individual (...

The compartmentalization of RanGAP (GTPase activating protein) and RanEGF (guanine nucleotide exchange factor) is the basis of the proposed predominance of RanGDP in the cytoplasm and RanGTP in the nucleus [64]. b Schematic diagram of the cycle model of protein molecules related to nuclear ...
to as the control center of the cell, wherein movement, reproduction and eating are being controlled. Although it is not commonly located in the center of the cell, it is basically a big dark spot found in the middle of the cytoplasm (cytosol), which is the fluid that fills the cells....
