The Cell Cycle G1 phase. The cell grows. S phase. The cell makes copies of its chromosomes. Each chromosome now consists of two sister chromatids. G2 phase. The cell checks the duplicated chromosomes and gets ready to divide. M phase. The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The period between cell divisions is known as 'interphase'. Cells that are not dividing leave the cell cycle and stay in G0.

The Cell Cycle- Chromosomes
Centriole = An organelle that helps in cell division. G1 phase. The cell grows. S phase. The cell makes copies of its chromosomes. Each chromosome now consists of two sister chromatids. G2 phase. The cell checks the duplicated chromosomes and gets ready to divide. M phase. The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The period between cell divisions is known as 'interphase'. Cells that are not dividing leave the cell cycle and stay in G0.
4
The Cell Cycle- G1 (Gap 1) 1. Create a cell and nucleus with the string. 2. Show the cell growing.
5
The Cell Cycle- S (dna Synthesis)
1. Make more DNA (double it).
6
The Cell Cycle- G2 (Gap 2) 1. Create a cell with the string.
2. Include a nucleus. 3. Organelles
7
Mitosis- Prophase 1. Make chromosomes from DNA. 2. DNA wound up
8
Mitosis- Metaphase 1. Chromosomes line up in middle.
9
Mitosis- Anaphase 1. Spindle fibers appear.
2. Spindle fibers pull apart chromosomes
10
Mitosis- Telophase 1. Pulls the chromosomes farther apart .
2. Nucleus reforms
11
Mitosis- Cytokinesis 1. Cell splits into cells.
12
The Cell Cycle- Interphase
1. Two identical cells. 2. Starts the cycle again.
13
Mitosis- Telophase 1. Pulls the chromosomes farther apart .
2. Nucleus reforms
14
The Cell Cycle- G2 (Gap 2) 1. Create a cell with the string.
2. Include a nucleus.
