what is the function and location of the nucleus?
47186
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material.

Nucleus and Nucleolus The nucleus determines how the cell will function, as well as the basic structure of that cell.
501001
Contains DNA, the cell's genetic material. Regulates the production of proteins required by each cell to carry out its function. Both animal and plant cells have a nucleus. Manufactures protein and may be found in the cytoplasm or attached to the endoplasmic reticulum.

The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

It is the control center of the cell bound by a double membrane known as the nuclear envelope, and is a porous membrane that allows substances to pass through it. The nucleus plays an important role in protein formation.

In eukaryotic cells, most DNA is located in the cell nucleus (though some DNA is also contained in other organelles, such as in the mitochondria and the chloroplast in plants). Nuclear DNA is organized into linear molecules called chromosomes.
1089209
In eukaryotic cells, chromosomes are located in the nucleus, and are made up of chromatin.
913875
In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

Nucleus. The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell.

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
468570
The protons and neutrons are found in the nucleus at the centre of the atom. The nucleus is very much smaller than the atom as a whole. The electrons are arranged in shells around the nucleus.

This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.

The nucleus has a double membrane (the nuclear envelope) around it. The nuclear membrane has pores allowing the movement of substances through it. The nuclear membrane joins up with the endoplasmic reticulum. The nucleus contains chromosomes which are made of DNA and associated proteins called histones.

The nucleus is the tiny, dense, central core of the atom and is composed of protons and neutrons. Rutherford's atomic model became known as the nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom.

It is located outside of the nucleus and within the cell membrane. Organelles: Organelles are tiny cellular structures that perform specific functions within a cell.
