Question

Where is the nucleus present?

Answer 1

The cell nucleus is defined as a film bound structure that contains the complete data of the cell and also controls the cell's development and reproduction. It can also be said as the war room of a eukaryotic cell and is generally the most noticeable organelle in a cell as it represents 10% of the cell's volume.

Complete answer:
In order to understand the location of the nucleus, first, we need to understand the structure of a nucleus. A nucleus mainly consists of a nuclear membrane, chromosomes, nucleoplasm, and nucleolus.

Nuclear Membrane: Nuclear Membrane is a double membrane that encloses the nuclear contents. The outer membrane layer connects with the endoplasmic reticulum whereas the nuclear envelope consists of a lipid bilayer compromising phospholipids.

Nucleoplasm: It is a gelatinous substance that is enclosed within the nuclear envelope. It basically represents the nucleoplasm. It is also well known as karyoplasm, nucleoplasm is a semi-aqueous material having dissolved salts, organic molecules, and enzymes suspended within the water.

Nucleolus: The nucleolus content of the nucleus is very dense in nature and it is also a membrane devoid structure consisting of RNA and proteins.

Chromosomes: The nucleus also known as organelle houses has chromosomes within it. The nucleus also contains some other non-membrane delineated bodies like polymorphic interphase karyosome association, Cajal bodies, paraspeckles and Gemini of coiled bodies.

Thus, the nucleus of the cell is present in the middle of the cytoplasm of the cell.

Note: A nucleus is basically a double membrane organelle that contains the genetic material and it also other instructions which are required for cellular processes. It is also exclusively found in the eukaryotic cells and is one of the largest organelles.
