cell cycle | The regular sequence of growth and division that cells undergo. |
interphase | The stage of the cell cycle that takes place before cell division occurs. |
replication | The process by which a cell makes a copy of the DNA in its nucleus. |
mitosis | The stage of the cell cycle during which the cell's nucleus divides into two new nucleiand one copy of the DNA is distributed into each daughter cell. |
