NUCLEAR DIVISION Meaning and
Definition
-
Nuclear division, also known as cell division, is a fundamental biological process that occurs within living organisms, resulting in the formation of two or more daughter cells. This process is crucial for growth, development, and repair of living tissues and is vital for the survival and reproduction of organisms.
During nuclear division, the genetic material within the cell's nucleus, which is composed of DNA molecules, undergoes a series of complex steps leading to its proper distribution among the daughter cells. This division ensures that each daughter cell receives an accurate copy of the genetic material present in the original cell, enabling genetic continuity.
There are two main types of nuclear division: mitosis and meiosis. Mitosis is the form of nuclear division responsible for the growth and maintenance of somatic cells, where a single cell divides into two identical daughter cells. Meiosis, on the other hand, is the process that occurs specifically in reproductive cells (gametes), resulting in the formation of cells with half the number of chromosomes as the parent cell.
Nuclear division is highly regulated and orchestrated by various molecular and cellular factors, ensuring the accurate distribution of genetic information. Defects or errors in nuclear division can lead to serious consequences, such as abnormalities, mutations, or cell death, highlighting the importance of this process in maintaining normal cellular functions.

Etymology of NUCLEAR DIVISION
The word "nuclear division" is derived from two main components:
1. "Nuclear": The word "nuclear" is derived from the Latin word "nucleus", which means "the central part". In the context of biology and cell biology, "nuclear" refers to the nucleus, which is the central organelle in eukaryotic cells that contains the genetic material.
2. "Division": The word "division" comes from the Latin word "divisio", which means "a separating or dividing". It refers to the act or process of splitting something into two or more parts.
Therefore, "nuclear division" refers to the process of dividing the nucleus during cell division. It is a crucial step in both mitosis (cell division that produces two identical daughter cells) and meiosis (cell division that produces gametes - sperm and eggs - with half the number of chromosomes).
