Mitosis Process

Cellular division through mitosis ensures growth and repair in organisms. The process begins with DNA replication during interphase, followed by four main phases prophase, metaphase, anaphase, and telophase. During these stages, chromosomes condense, align at the cell's equator, and separate into two identical daughter cells. Complex protein structures guide chromosome movement and cell division.

Meiosis Formation

Meiosis creates reproductive cells through two sequential divisions, reducing chromosome number by half. This process introduces genetic variation through crossing over and random chromosome assortment. The resulting gametes contain unique genetic combinations, essential for sexual reproduction. Errors in meiosis can lead to chromosomal abnormalities affecting offspring.

Cell Cycle Control

Cellular division is regulated by checkpoints ensuring proper DNA replication and chromosome separation. Growth factors and environmental conditions influence division timing. Cancer can result from disrupted cell cycle controls, leading to uncontrolled division. Understanding these regulatory mechanisms helps develop treatments for diseases involving abnormal cell division.Shutdown123
