Cell Division

Cell Division

Introduction

Cells in our body always grow, divide and die.
As such, the dead cells must be replaced with new cells.
Cells in the body produce new cells through the cell division process.
Cell division involves two stages, that is karyokinesis and cytokinesis.
Karyokinesis involves the division of the nucleus.
Cytokinesis involves the division of the cytoplasm.
The organism’s body cells are divided into somatic cells and reproductive cells or gametes.
In diploid cells, one set of chromosomes originate from the male parent or paternal chromosomes and another set is from the female parent or maternal chromosomes.
Both paternal and maternal chromosomes have the same structural characteristics.
This pair of chromosomes are called homologous chromosomes.
Chromatin is a chromosome that looks like a long thread.
