Chapter 11 Cell Reproduction

The cell cycle is the series of events from the time a cell forms until its cytoplasm.

Interphase is a three step process between mitotic divisions when a cell grows. The 3 steps are G1, S, and G2. G1 = metabolic activities (cell growth) S = DNA synthesis (2 x DNA). G2 = protein synthesis needed for cell division (checkpoint)

Prophase is the first stage of mitosis , before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.

Metaphase is one of the final stages in mitosis between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.

Anaphase is one of the final stages of 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 to from 2 nuclei.

Telomeres are noncoding repeat DNA sequences (repeated thousands of times) found at the ends of eukaryotic chromosomes.

Cancer is a mutation in multiple checkpoint genes are required to transform a normal cell into a malignant one. Such mutations may take a lifetime to accumulate
