First Foldable: The Cell Cycle Page 41 in your notebook

Flap 1: Gap 1 (G1) - First stage of the cell cycle - Cell carries out normal functions - Cell increases in size, organelles increase in numbers

Flap 2: Synthesis (s) - Second stage of the cell cycle - The cell makes an identical copy of the DNA in the nucleus

Flap 3: Gap 2 (G2) - Third stage of the cell cycle - Additional growth occurs - Cell goes through a critical checkpoint to make sure everything is in order

Flap 4: Mitosis - Final stage of cell cycle - Division of the cell to create two identical daughter cells - Ends with cytokinesis, the division of the cell cytoplasm

Second Foldable: Mitosis Page 42 in your notebook

Flap 1: Prophase - DNA and proteins condense into chromosomes - The nucleus begins to break down - Centrioles move to opposite poles - Spindle fibers form

Flap 2: Metaphase - Spindle fibers attach to each chromosome - Chromosomes line up along the middle of the cell

Flap 3: Anaphase - Chromatids (halves of the chromosomes) separate and move to opposite side of the cell

Flap 4: Telophase - Two new nuclear membranes form - Chromosomes begin to uncoil - Spindle fibers fall apart - Cytokinesis occurs, dividing the cytoplasm between the two daughter cells
