In Model 1, if the length of the arrow represents time, then for those cancerous cells, what hap pens to the time that is necessary for the cell cycle? What implication might this have for doctors who are treating cancer patients? Why? Living things must grow and develop. At times they suffer injuries or damage, or cells simply wear out. New cells must be formed for the organism to survive. What process must occur to make a new, properly- functioning cell?

In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?
Tumor suppressor genes _____. a. occur normally in cells b. promote metastasis c. are brought into cells by viruses d. only rarely affect the development of cancer
____________ is the process through which a tumor supports its growth by creating its own blood supply. metastasis angiogenesis neoplasm malignant tumor
HeLa Cells Are a Genetic Mess HeLa cells can vary in chromosome number. Defects in proteins that orchestrate cell division result in descendant cells with too many or too few chromosomes, an outcome that is one of the ha1lmarks of cancer cells. The panel of chromosomes in FIGURE 11.9, originally published in 1989, shows all of the chromosomes in a single metaphase HeLa cell. FIGURE 11.9 Karyotype of HeLa showing chromosomes in one cell. What is the chromosome number of this HeLa cell?
Which of the following is not a characteristic of cancer cells? a. less cytoplasmic volume than normal cells b. an absence of cyclin c. loss of adhesion to other cells d. loss of control of cell division e. loss of normal control of G1/S phase transition
Cervical Cancer Incidence In HPV-Positive Women In 2003, Michelle Khan and her coworkers published their findings on a 10-year study in which they followed cervical cancer incidence and HPV status in 20,514 women. All women who participated in the study were free of cervical cancer when the test began. Pap tests were taken at regular intervals, and the researchers used a DMA probe hybridization test (Section 15.3) to detect specific types of HPV in the women's cervical cells. The results are shown in FIGURE 37.26 as a graph of the incidence rate of cervical cancer by HPV type. HPV- positive women are often infected by more than one type, so the data were sorted into groups based on the women's HPV status ranked by type: either positive for HPV16; or negative for HPV16 and positive for HPV18; or negative for HPV16 and HPV18 and positive for any other cancer-causing HPV; or negative for all cancer-causing HPV. Follow-up time (months) FIGURE 37.26 Cumulative incidence rate of cervical cancer correlated with HPV status in, 20,514 women aged 16 years and cider. The data were grouped as follows: HPV16 positive HFV16 negative and HPV18 positive All other cancer-causing HPV Types combined No cancer-causing HPV type was detected. 1. At 110 months into the study, what percentage of women who were not infected with any type of cancer-causing HPV had cervical cancer? What percentage of women who were infected with HPV16 also had cervical cancer?
