Cell Cycle
Vocab
| Term | Definition |
|---|---|
| CHROMATIN | Relaxed form of DNA in the nucleus of a cell |
| CHROMOSOME | DNA-containing-structure that carries genetic material from one generation to another |
| CYTOKINESIS | A cell's cytoplasm divides, creating a new cell |
| INTERPHASE | The stage in which the cell grows, carries out cellular functions, and replicates its DNA |
| MITOSIS | The stage of the cell cycle. The cell's replicated DNA divides and 2 identical diploid daughter cells are produced. |
| CENTROMERE | The structure at the center of the chromosome where the sister chromatids are attached. |
| METAPHASE | During the 2nd stage of mitosis in which motor proteins pull sister chromatids to the cell's equator. |
| PROPHASE | The 1st stage of mitosis during which the cell's chromatin condenses into chromosomes. |
| SISTER CHROMATID | Structure that contains identical DNA copies and is formed during DNA replication. |
| SPINDLE APPARATUS | Structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides. |
| TELOPHASE | Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has n t yet completely divided. |
| ANAPHASE | The 3rd step of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell. |
