Question

What is nucleus [ no spam]

Answer 1

Answer:

The nucleus is an organelle found in most eukaryotic cells, the exception being red blood cells. In animal cells it is both the largest and stiffest organelle and is easily identifiable by light microscopy. The average mammalian nucleus has a diameter of ~6µm and occupies about 10% of the total cell volume.

Explanation:

Function

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

Charge

Composition of the Atom. The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.

How to find

A nucleus is identified as in the example below by its atomic number Z (i.e., the number of protons), the neutron number, N, and the mass number, A, where A = Z + N. The convention for designating nuclei is by atomic number, Z, and mass number, A, as well as its chemical symbol.
