1.Mitosis is done by your body cells. What types of cells do not undergo mitosis?
Sperm cells and egg cells do not undergo mitosis. They undergo a different process of cell division called meiosis. The difference between the two types of cell division is that mitosis result in a replication of the parent cell or identical cells. Meiosis contributes to genetic variety, meaning the resulting cells are different from the parent cell in some way.
2.Describe ways that mitosis is important for your body.
Mitosis is important for growth. Mitosis creates new cells as you grow. If you think about it, where do we get all the extra skin, longer bones, longer hair—they result from the division of cells which create new cells.
Another way it is important is in repair. When you get a cut for example, mitosis helps by producing more cells to repair the gash that was left. New cells fill in the part that was cut. Mitosis also helps with replacing worn out cells.
3. This illustration is trying to demonstrate something that mitosis is not. In mitosis, the cells that are created are identical.
The illustration shows that one type of cell produces a different type, but it is not the case with mitosis. The resulting cells of this type of cell division is identical or twins.
4.Mitosis is just one small part of the cell cycle! Describe what would occur if cells were in mitosis more than they were in interphase.
Interphase makes up most of the cell cycle, it makes up about 90% and mitosis occurs in 10% of the whole cycle. If cells were in mitosis more than they were in interphase that would indicate an uncontrollable and rapid growth of cells and you can get cancer.
5.When cells are dividing, it is important to understand that they have to move chromosomes equally to both cells. Based on this illustration, describe what a chromosome is made of.
Chromosomes are condensed units found in the nucleus. There are 46 chromosomes each nucleus, or each cell. Chromosomes are made up of protein and DNA. DNA stands for deoxyribonucleic acid and it carries genetic information.
6. In humans, there are 46 chromosomes. They are duplicated during interphase, which in turn duplicates the DNA as well. Chromosomes are counted based on the number of centromeres. The number of chromosomes in living organisms or species differ from each other.
- Sperm cells and egg cells do not undergo mitosis.
- Mitosis is important for growth.
- The resulting cell of mitosis for cell division is identical or twins.
- If a cell spends more time in M-phase (in which the mitotic division takes place) than interphase (it is a metabolic phase of the cell), it would indicate the uncontrollable and rapid growth of cells.
- Chromosomes consist of DNA and protein.
- In humans, there are 46 chromosomes.
Further Explanation:
Mitosis produces two daughter cells that are genetically identical and maintain the consistency of chromosomes. Mitosis occurs in somatic cells. The crossing over between the homologous chromosomes is absent. The stage of occurrence of order includes prophase, prometaphase, metaphase, anaphase and telophase. The process of mitosis does not occur in the germ cell. Mitosis forms two daughter cells that are genetically similar and maintain the consistency of chromosomes.
Meiosis is a reductional cell division where the haploid chromosome containing four daughter cells are formed. Meiosis is a highly organized cell division as the gamete or spore produce must contain one member of each “homologous pair” of chromosomes. The crossing over results in genetic exchange between non-sister chromatids of “homologous chromosomes.” Interphase is a part of the cell cycle; it makes up about 90% and mitosis occurs in 10% of the whole cycle. If cells stay in M-phase more than the interphase of the cell cycle, which means the cells are showing uncontrollable growth that would result in cancer.
Chromosomes consist of DNA that is tightly packed around histone protein. A chromosome with similar length, same gene location, centromere placement and staining pattern; are known as homologous chromosomes. Chromosomes have a constricted area, which is called a centromere. The location of the centromere determines the shape and type of chromosome. Each chromosome has two arms p arm and a q arm. Chromosomes can be of different types like metacentric, acrocentric and telocentric.
