Questions:
1 . By which phase of mitosis do each of the following occur:
a. Centromeres divided and chromosomes move toward opposite sides of the cell anaphase
b. Chromatin coils to create visible chromosomesprophase
c. The nuclear membrane disappearsprophase
g. Sister chromatids line up in the heart of the cellmetaphase
2 . By which phases of mitosis are sister chromatids visible, and attached to one another at the centromere?
Prophase and metaphase
a few. What does your data indicate regarding the rate of cell section in cancer tissue when compared to rate of cell split in regular tissue? What data would you use to resolve this issue? The mitotic index shows that the rate of cell department has incresed in cancer cells.
4. Which kind of tumor is the quickest growing? Describe your solution, using your relevant data. The fastest growing cancer is definitely ovarian tumor. It has the greatest Mitiotic index.
5. Using what you have noticed in this lab, if you were to compare tissue sample via normal breast growth and cancerous breast tissue:
a. Would you be ready to see a difference in the level of cellular division inside the cancerous breast tissue compared to the usual breast tissue? Describe your response. Yes, cancerous tissue provides a higher mitotic index than non cancer tissue.
n. Could you make a prediction about the regular % separating cells inside the cancerous breast growth? Explain the answer. Based on the other tissue trials I would estimation a mitiotic index between 23 and 40.
6th. Consider the % separating cells in normal lung, normal belly, and typical ovarian tissue. Why do you think there are more cells dividing in the tummy and ovary tissue than in the lung tissue?
The stomach has a high turn over of cellular material due to foodstuff, acid, and churning in the stomach. Ovarian cells are constantly reproducing as part of the menstrual period.
7. This kind of lab is exploring three prevalent cancers. Yet another form of cancer ” Skin area Cancer ” used to be observed only in older individuals but is actually seen in younger individuals, various in their early on 20s. Epidermis cancer results from accumulated changement to the GENETICS of pores and skin cells, caused primarily by simply sun direct exposure. What elements do you think could possibly be contributing to the increase in skin area cancer among young adults?
The increased rates could be because of exposure to a greater amount of carcinogens like UV Rays and toxins in the environment.
