Term | Definition |
---|---|
mitoses | a proceess in which the nucleus and the chromosomes of the cell divides to create two cells that are exact copies of the original cell. |
Replication | the process in which the DNA is copied |
Cell Cycle | regular sequence of growth and divisions that a cell undergoes in its life span |
Cytokinesis | The stage of the cell cycle in which the cytoplasm divides. |
Chromosomes | Threadlike structures in the nucleus that carry the genetic information |
Genes | A section of chromosome that carries the code for a trait. |
Asexual Reproduction | A reproductive process that involves only one parent and the offspring are identical to the parent. |
Daughter Cells | The two cells produced from the parent cell by mitosis. |
DNA | Makes up the chromosomes, contains the genetic information, the genes. |
Interphase | longest phase, cell grows, matures and does its job. DNA is copied. |
Prophase | Chromosomes appear. Nucleur membrane breaks down. Spindle fibers appear. |
Metaphase | Chromosomes attach to the spindle fibers at the centromere. Chromosomes line up in the center of the cell. |
Anaphase | Chromosomes are pulled apart and move to opposite ends(poles) of the cell. One of each pair of sister chromatid is at each end of the cell. |
Telophase | Nucleur membrane reforms and the cell begins to pinch in (animal cell). |
