- 1MitosisMitosis is the stage between G2 and Cytokinesis. It is the division of cell that repairs lost cells in the body.
- 2MeiosisMeiosis is the stage of the cell cycle between G2 and Cytokinesis.
Meiosis creates 4 cells that are all genetically different that are all haploid. - 3Mitosis: Stage 1- DNA SynthesisEach piece of chromatid in the cell is paired with an opposite chromatid.
- 4Mitosis: Stage 2- ProphaseThe chromosomes become visible and the nuclear membrane breaks down.
- 5Mitosis: Stage 3- MetaphaseThe chromosomes line up along the equator (middle) of the cell. The centrioles attach to each chromosome.
- 6Mitosis: Stage 4- AnaphaseThe centrioles pull apart the chromosome into chromatids and they get pulled to the poles of the cell.
- 7Mitosis: Stage 5- TelephaseThe cell develops a cleavage furrow. Both new cell develop a nucleus and the DNA uncoils into chromatin.
- 8Mitosis: Stage 6 and 7- CytokinesisThe cytoplasm divides to make two new identical cells.
- 9Meiosis: Stage 1- Prophase 1The chromosomes become visible. The spindle fibers appear. Nuclear membrane dissolves. The chromosomes begin crossing over
- 10Meiosis: Stage 2- Metaphase 1The homologous pairs line up along the equator and attach to the spindle fibers.
- 11Meiosis: Stage 3- Anaphase 1The spindle fibers begin to pull the chromosomes to the poles of the cell.
- 12Meiosis: Stage 4- Telephase 1The cell develops a cleavage furrow and form two nucleuses with the genetically different chromosome in each cell.
- 13Meiosis: Stage 5- InterkinesisThe cells divide their cytoplasm.
- 14Meiosis: Stage 6- Prophase 2The two new cell's chromosomes begin to appear and the nuclear membrane dissolves. Both cells now have half the chromosome they had in Prophase 1.
- 15Meiosis: Stage 7- Metaphase 2The chromosomes line up single file in both cells.
- 16Meiosis: Stage 8- Anaphase 2The chromatids then get separated to the poles of the cell.
- 17Meiosis: Stage 9- Telephase 2Both cells develop a cleavage furrow and new nuclei.
- 18Meiosis: Stage 10- CytokinesisBoth divide their cytoplasm and make four genetically different cells.
- 19The goal of MitosisThe goal of Mitosis is to make somatic cells. In Mitosis we need to make a complete copy of our DNA and then divide to make two identical new cells.
- 20The goal of MeiosisThe goal is to create four genetically different cells that are all haploid or n.
- 21Mitosis setsIn Mitosis you make a diploid set of chromosome
- 22Meiosis setsIn Meiosis you start off with 4n in Prophase 1 and by the time you finish you have n in each cell.
- 23Crossing Over: MeiosisIn Meiosis during Prophase 1 the cell's chromosome cross each parent chromosome pairs with the other parent chromosome.
- 24Meiosis DNAThe cells in meiosis increase in size and mature. There is NO S PHASE. DNA is not copied.
- 25Mitosis: Cytokinesis in Plants and AnimalsIn animal cells they develop a cleveage furrow and spilt in half. In plant cell a cell plate develops so that a new cell wall can develop.
- 26Principle of Random Fertilization (Meiosis)The combination of sperm and egg is random in meiosis.
- 27Principle of Independent AssortmentWhen chromosomes arrange themselves in metaphase 1 or 2 they are randomly distributed.
- 28Mitosis and Meiosis in Cell CycleDuring Mitosis or Meiosis the DNA condenses into chromosomes.
- 29DNA in Mitosis and MeiosisDNA is being divided not the cell.
- 30Meiosis DNABefore Meiosis begins the DNA in the original cell is replicated creating the 4n set of chromosomes.
