| cell cycle | regular sequence of growth and division that cells undergo |
| interphase | first stage of the cell cycle: the cell grows, makes a copy of its DNA, and prepares to divide into two cells |
| replication | the cell makes an exact copy of the DNA in its nucleus |
| mitosis | stage during which the cell's nucleus divides into two new nuclei: one of the DNA is distributed into each of the two daughter cells |
| chromosomes | during mitosis, the threadlike chromatin in the nucleus condenses to form double-rod structures called... |
| cytokinesis | final stage of the cell cycle: the cytoplasm divides and the organelles are distributed into each of the two new cells. |
| nucleus | the control center of the cell |
| nitrogen bases | molecules that contain the element nitrogen and other elements |
| 4 nitrogen bases of DNA | adenine, thymine, guanine, and cytosine (A,T,G, and C) |
| In DNA replication, Adenine pairs with... | Thymine |
| In DNA replication, Guanine pairs with... | Cytosine |
