Nucleus

Scientist have examined the structure of the two main types of cells: prokaryotic and eukaryotic cells. Now we turn our attention to the "nerve center" is a eukaryotic cell nucleus.

Nucleus is a membrane-bound structure that genetic information in cells and controlling cell growth and multiplication contains.

It is often the most prominent cell organelle.
Differences in characteristics:
core bounded by a double membrane called the nuclear envelope. This membrane separates the contents of nuclei from cytoplasm.

envelope helps to form the core and helps the flow of molecules in and out of the nucleus to regulate through nuclear pores.

Chromosomes in the nucleus.

When the cell is "resting", which is not shared, chromosomes are organized into long entangled structures called chromatin, rather than the individual chromosomes, as we usually think of them.
Nucleolus:
kernel is the nucleolus that helps synthesize ribosomes.

nucleolus contains the nucleolar organizers, which are part of the chromosome with the provisions of the synthesis of ribosomal genes. Large amounts of RNA and protein can be found in nucleolus, as well.

nucleus controls the synthesis of proteins in the cytoplasm, the messenger RNA. Messenger RNA is produced from the cell nucleolus and travels to the cytoplasm through the pores of the nuclear envelope.
