Question | Answer |
Mitosis | Mitosis is the stage between G2 and Cytokinesis. It is the division of cell that repairs lost cells in the body. |
Meiosis | Meiosis is the stage of the cell cycle between G2 and Cytokinesis. Meiosis creates 4 cells that are all genetically different that are all haploid. |
Mitosis: Stage 1- DNA Synthesis | Each piece of chromatid in the cell is paired with an opposite chromatid. |
Mitosis: Stage 2- Prophase | The chromosomes become visible and the nuclear membrane breaks down. |
Mitosis: Stage 3- Metaphase | The chromosomes line up along the equator (middle) of the cell. The centrioles attach to each chromosome. |
Mitosis: Stage 4- Anaphase | The centrioles pull apart the chromosome into chromatids and they get pulled to the poles of the cell. |
Mitosis: Stage 5- Telephase | The cell develops a cleavage furrow. Both new cell develop a nucleus and the DNA uncoils into chromatin. |
Mitosis: Stage 6 and 7- Cytokinesis | The cytoplasm divides to make two new identical cells. |
Meiosis: Stage 1- Prophase 1 | The chromosomes become visible. The spindle fibers appear. Nuclear membrane dissolves. The chromosomes begin crossing over |
Meiosis: Stage 2- Metaphase 1 | The homologous pairs line up along the equator and attach to the spindle fibers. |
Meiosis: Stage 3- Anaphase 1 | The spindle fibers begin to pull the chromosomes to the poles of the cell. |
Meiosis: Stage 4- Telephase 1 | The cell develops a cleavage furrow and form two nucleuses with the genetically different chromosome in each cell. |
Meiosis: Stage 5- Interkinesis | The cells divide their cytoplasm. |
Meiosis: Stage 6- Prophase 2 | The 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. |
Meiosis: Stage 7- Metaphase 2 | The chromosomes line up single file in both cells. |
Meiosis: Stage 8- Anaphase 2 | The chromatids then get separated to the poles of the cell. |
Meiosis: Stage 9- Telephase 2 | Both cells develop a cleavage furrow and new nuclei. |
Meiosis: Stage 10- Cytokinesis | Both divide their cytoplasm and make four genetically different cells. |
The goal of Mitosis | The 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. |
The goal of Meiosis | The goal is to create four genetically different cells that are all haploid or n. |
Mitosis sets | In Mitosis you make a diploid set of chromosome |
Meiosis sets | In Meiosis you start off with 4n in Prophase 1 and by the time you finish you have n in each cell. |
Crossing Over: Meiosis | In Meiosis during Prophase 1 the cell's chromosome cross each parent chromosome pairs with the other parent chromosome. |
Meiosis DNA | The cells in meiosis increase in size and mature. There is NO S PHASE. DNA is not copied. |
Mitosis: Cytokinesis in Plants and Animals | In 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. |
Principle of Random Fertilization (Meiosis) | The combination of sperm and egg is random in meiosis. |
Principle of Independent Assortment | When chromosomes arrange themselves in metaphase 1 or 2 they are randomly distributed. |
Mitosis and Meiosis in Cell Cycle | During Mitosis or Meiosis the DNA condenses into chromosomes. |
DNA in Mitosis and Meiosis | DNA is being divided not the cell. |
Meiosis DNA | Before Meiosis begins the DNA in the original cell is replicated creating the 4n set of chromosomes. |
