The Cell Cycle
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.
Interphase is the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis. Also known as the "G 1" phase of the Cell Cycle, this is the stage where the initial growth of the cell takes place.
Prophase is the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
Metaphase is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
Anaphase is the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
Telophase is the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
Telomeres is a region of repetitive nucleotide sequences at each end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes.
Cancer cells are cells that divide relentlessly, forming solid tumours or flooding the blood with abnormal cells.
