Summary Introduction

To analyze:

Michelle Khan and her coworkers studied cervical cancer and human papillomavirus (HPV) status in 20,514 women for 10 years and published their findings in 2003. They performed papanicolaou test at regular intervals, and the DNA probe hybridization test was performed to detect the presence of a specific type of HPV in the women’s cervical cells. No woman was infected with cervical cancer when the test began.

The percentage of women at 110 months, not infected with any type of cancer-causing HPV, had cervical cancer, and the percentage of women suffering from cervical cancer also had HPV16 infection, is to be analyzed from the graphs of their published results, given below.

The results for Michelle and her coworkers’ studies are shown in a graphical pattern below:

Introduction:

Cervical cancer is a major type of cancer found in women, mainly caused by a virus called the human papilloma virus (HPV). This virus causes cancer in the cervical cells of the uterus. There are more than 100 strains of HPV present, but only a few causes cervical cancer. The most commonly noticed cervical cancers are caused by HPV16 and HPV18.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)   Data Table 1Stage    Totals    PercentInterphase        Mitosis:        Prophase        Metaphase        Anaphase        Telophase        Cytokinesis        Totals    100    100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
