1. The Cell Cycle
Foldable

2. Pick up handout! New unit, new vocabulary!!!
Copy down vocabulary words on page 25 of notebook
Anaphase Cytokinesis Interphase Transcription
Cell cycle Daughter cell M phase Deoxyribonucleic Acid (DNA)
Centriole Diploid Metaphase
Centromere DNA replication Mitosis
Chromatid G1 phase Prophase
Chromosome G2 phase S phase

3. 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

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

6. The cell cycle

7. 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

8. G1 Phase Typically the longest phase of the entire cell cycle
The cell grows and produces cell components
The DNA is loosely spread out, and you can’t see individual chromosomes (chromatin form)

9. S Phase DNA is replicated
Every DNA molecule is copied exactly, forming 2 sister chromatids that stay attached to each other

10. G2 Phase Cell prepares for division
Makes the cytoskeleton proteins it needs to move the chromosomes around

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

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

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

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

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

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