Glencoe Cell Cycle and Cancer Virtual Lab
I would expect that cancerous breast tissue has a higher rate of cell division than normal breast tissue because cancer cells have a higher mitotic index b. Table 1: Record your data for the number of cells in each stage of the cell cycle observed in normal tissues. You will choose from all six normal or cancerous tissues. Why do you think there are more cells dividing in the stomach and ovary tissue than in the lung tissue? Virtual Lab: The Cell Cycle and Cancer Worksheet 1. To find my answer I subtracted the ovary % from the stomach % 21.

Consider the % dividing cells in normal lung, normal stomach, and normal ovarian tissue. Ask the students to consider accuracy, neatness, creativity and colorfulness as they develop their pamphlet. Why do you think there are more cells dividing in the stomach and ovary tissue than in the lung tissue? Sister chromatids line up in the center of the cell 2. Explain your answer, using your relevant data.
The activity should take no more than one hour and some students may wish to try the technique on prepared slides of onion or garlic root tip cells as an extension activity. In which phases of mitosis are sister chromatids visible, and attached to each other at the centromere? Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Based on the data in the average percentage of dividing cells, the lung cancerous tissue has more cells in the interphase, which means these cells are dividing slower than the other types of cancerous tissues. In animal cells the centrioles duplicate themselves.

I think younger adults might not be unaware, or even ignorant about the possible risk of developing skin cancer.
Virtual Lab: The Cell Cycle and Cancer Worksheet 1. In which phase of mitosis do each of the following occur: a. Difficult to be exact but probably higher than 10% mitotic index since mitotic index of normal cells seems to be between 5-7. Dives Drive Ins and Dives San Francisco st joseph hospital careers ann arbor craigslist chicago western suburbs furniture, most marriages end in divorce when do you start dating someone. It is important to study cancer because it could Hypothesis I believe normal cells will look different than cancerous cell tissues with regard to phases of the cell cycle in that cancerous cells will be mostly in m phase and normal cells in will be mostly in interphase because cancerous cells divide more than normal cells.
