The Cell Cycle Foldable 10-18-2018

Pick up all both handouts Put Cell Cycle and DNA Pacing calendar on page 1 in your notebook RIGHT NOW We will complete the pictures on foldable together Then you will use powerpoint to complete definitions

The Cell Cycle Foldable Today we will go over the cell cycle by creating a foldable Take your handout and fold it in half so that it looks like this The Cell Cycle Mitosis cytokinesis Interphase

The cell cycle The life of a cell The alteration between dividing and not dividing

Interphase The nondividing part of the cell cycle The nuclear membrane is intact throughout interphase Split into 3 phases G1 phase, S phase, and G2 phase

G1 Phase Growth phase The longest phase of the cell cycle The DNA is loosely spread out

S Phase Synthesis phase DNA is replicated 2 sister chromatids are formed, attached at the centromere

G2 Phase 2nd Growth Phase Cell prepares for division Makes the spindle fibers it needs to move chromosomes around

Mitosis Division of genetic material and nucleus of the cell leading up to cell division

Prophase DNA appears as chromatin coils that pair up as they condense Nuclear membrane disappears

Metaphase Chromatid pairs line up along the middle of the cell Centrioles form spindle fibers attaching the chromatid pairs at their centromeres

Anaphase Chromatid pairs separate and are pulled towards the cells poles by the spindle fibers

Telophase Cells get ready to divide into two by forming new nuclear membranes around the separated sets of chromosomes

Cytokinesis After mitosis ends Cytoplasm and organelles of the cell divide forming two identical cells
