Cell nucleus - Wikipedia
The eukaryotic cell nucleus. Visible in this diagram are the ribosome-studded double membranes of the nuclear envelope, the DNA (complexed as chromatin), and the nucleolus. Within the cell nucleus is a viscous liquid called nucleoplasm, similar to the cytoplasm found outside the nucleus.

The Nucleus - Definition, Structure, and Function
The nucleus regulates the synthesis of proteins in the cytoplasm through the use of messenger RNA (mRNA). Messenger RNA is a transcribed DNA segment that serves as a template for protein production. Messenger RNA is a transcribed DNA segment that serves as a template for protein production.

The nucleus is the organelle responsible in maintaining the integrity of DNA and in controlling cellular activities such as metabolism, growth, and reproduction by regulating gene expression. The nucleus has three main components: the nucleolus, the chromatin and the nuclear envelope.
Nucleus | definition of nucleus by Medical dictionary
1. cell nucleus; a spheroid body within a cell, contained in a double membrane, the nuclear envelope, and containing the chromosomes and one or more nucleoli. The contents are collectively referred to as nucleoplasm. The chromosomes contain deoxyribonucleic acid (DNA), which is the genetic material that codes for the structure of all the proteins of the cell.

Nucleus - definition of nucleus by The Free Dictionary
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 bacteria, which do not contain nuclei. See more at cell.
