A Closer Look at the Nucleus: Chromosomes DNA is the blueprint for life. A cell's DNA contains all of the information necessary to make a new cell and carry out its life processes. A cell's DNA normally exists in long, coiled, spaghetti-like strands inside the nucleus. Chromosomes Each individual strand of DNA is called a chromosome Before a cell can divide to form two new identical cells, it must make an exact copy of each chromosome Chromosomes in Mitosis The process of cell division is called mitosis When a cell divides, the chromosomes condense and become visible http://www.youtube.com/watch?v=N5zFOScowqo Chromosomes in Mitosis After the cell is finished dividing, the two new cells are called daughter cells Each daughter cell contains one copy of every chromosome from the original cell.
