Launch
Get out the following four assignments for your homework packet -Review Sheet from Monday -Enzyme Letter from Tuesday -Enzyme Worksheet from Tuesday -Cell cycle worksheet from Thursday
If time answer the following question:What are the three main stages of the cell cycle
and what happens in each?

MITOSISThe process a cell uses to copy its
DNA and create two identical daughter cells
![Page 4: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/4.jpg)
Pre-Mitosis: INTERPHASE
This is where the cell spends most of its time
Cell grows, gain nutrients, copies DNA
DNA is “just chillin” in the nucleus
![Page 5: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/5.jpg)
Interphase = In-between
![Page 6: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/6.jpg)
Step 1: PROPHASE
DNA condenses into chromosomes
Chromosomes pair up with their exact copy
Nucleus breaks down
![Page 7: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/7.jpg)
Prophase = Pairs
![Page 8: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/8.jpg)
Step 2: METAPHASE
Chromosomes line up in the middle of the cell
Chromosomes are attached to fibers that stretch from the poles to the middle of the cell

Metaphase = Middle

Step 3: ANAPHASE
The stage when chromosomes separate
Each singular chromosome pulled to opposite sides of the cell by fibers in the cell
![Page 11: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/11.jpg)
Anaphase = Apart
![Page 12: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/12.jpg)
Step 4: TELOPHASE
Cell membrane pinches off to form two cells
Nuclear envelope reforms around DNA
Chromosomes uncondense
![Page 13: 1 8 Mitosis](https://reader035.fdocuments.in/reader035/viewer/2022070316/555cb959d8b42a5f718b4635/html5/thumbnails/13.jpg)
Telophase = Two Cells
