The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. The B period extends from the end of cell division to the beginning of DNA replication. DNA replication occurs during the C period. The D period refers to the stage between the end of DNA replication and the splitting of the bacterial cell into two daughter cells. Mitosis and meiosis are the main events of the cell cycle that assure reproduction of cells.
The process of meiosis affirms genetic continuity from a parent to a child, while mitosis affirms a genetic clone from one cell to the next. Meiosis takes place in order for sexual reproduction to occur, while mitosis regulates growth and repair among cells and tissue. Additionally, meiosis gives rise to haploid Generally, both processes incudes: interphase, prophase, metaphase, anaphase and telophase as their main steps during divisions. However this essay will be particularly focusing on the process of mitosis.
