When the exact copying of the genetic code during cellular division is disrupted, producing a genetic variation from the parent cell, the result is called a mutation. Mutations can occur due to errors in DNA replication, environmental factors, or exposure to certain chemicals. These genetic changes can lead to variations in traits, which may be beneficial, neutral, or harmful to the organism.
Genes that encourage cell division are typically referred to as proto-oncogenes. These genes promote normal cell growth and division by producing proteins that drive the cell cycle and facilitate cellular proliferation. When proto-oncogenes undergo mutations or are overexpressed, they can become oncogenes, potentially leading to uncontrolled cell division and cancer development.
They need to reproduce,increase in size. Also need to repair damaged cells

mitosis
Cell division allows organisms to grow by producing more cells. It also helps in repairing damaged structures by replacing old or injured cells with new ones. However, cell division itself does not directly produce energy, as energy production is carried out by cellular processes such as respiration.
Three cellular processes are cell division (including mitosis and meiosis), protein synthesis (transcription and translation), and cellular respiration (producing energy from nutrients).

Meiosis is the type of cell division responsible for producing haploid cells.
DNA is copied in the S-Phase of cellular division through a process known as mitosis. It does so by duplicating each chromosome in anticiaption of cell division.
The control center of the cell necessary for cell division and cell life is the nucleus. It contains the genetic material (DNA) that regulates cellular functions and directs cell division. The nucleus also houses the nucleolus, which is responsible for producing ribosomes essential for protein synthesis.
