DIVISION IN EUKARYOTES
Two types of Cell Division for eukaryotes:Mitosis and Meiosis
![Page 3: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/3.jpg)
MITOSIS (DIVISION OF THE NUCLEUS) Occurs in organisms undergoing
growth, development, and repair One cell division Makes 2 new cells identical to the original
cell Makes somatic cells Makes diploid cell (2n)

MEIOSIS
Meiosis (gamete production) = Occurs during the reproduction of gametes (sex cells) Two cell divisions makes 4 new cells with half the
genetic material of the original Makes sex cells Makes haploid cells (n)

CELL CYCLE
Cell Cycle = A repeating cycle of events in the life of a cell
![Page 7: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/7.jpg)
CELL CYCLE
Interphase = the period between cell divisions (made of 3 phases)
![Page 8: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/8.jpg)
CELL CYCLE
Interphase = the period between cell divisions (made of 3 phases)
1) G1 = the growth phase, a new cell grows to mature size
2) S = DNA is copied or synthesized to prepare for division
3) G2 = the time when the cell prepares for division
![Page 9: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/9.jpg)
CELL CYCLE
Optional**) G0 = following G1 a cell can exit the cell cycle and prevent further cell division
• Ex/ Developed nerve cells enter G0 so nerve cells can not divide to repair damage

MITOSIS PHASES
Mitosis divides the cell’s nucleus in four phases.
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase
![Page 11: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/11.jpg)
MITOSIS PHASES
1. Prophase: Chromosomes condense, nucleus breaks down, and spindle fibers form
![Page 12: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/12.jpg)
MITOSIS PHASES
2. Metaphase: Chromosomes line up in the middle of the cell
![Page 13: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/13.jpg)
MITOSIS PHASES3. Anaphase: sister chromatids separate to
opposite sides of the cell.
![Page 14: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/14.jpg)
MITOSIS PHASES
4. Telophase: The new nuclei form, spindle fibers break down, and chromosomes begin to uncoil.

MITOSIS PHASES
Cytokinesis: division of the cytoplasm
![Page 16: 6-2 NOTES: MITOSIS AND CELL CYCLE. DIVISION IN EUKARYOTES Two types of Cell Division for eukaryotes: Mitosis and Meiosis](https://reader030.vdocuments.net/reader030/viewer/2022032722/56649ce35503460f949afb66/html5/thumbnails/16.jpg)
