- Shown here are two HeLa cancer cells that are just completing cytokinesis. Explain how the cell division of cancer cellslike these is misregulated. Identify genetic and other changesthat might have caused these cells to escape normal cell cycleregulationCancer Cell Cycle Describe the cell cycle is affect and support the saying “Cancer is the cell cycle disease” using the terms belowCheck pointsApoptosisMitosisFeedback FailureBPA is a chemical compound that has historically been used in themanufacture of plastic products. However, cells often mistake BPAcompounds for hormones that accelerate the cell cycle. Because ofthis, BPA is associated with an increased risk of certain cancers. Question: Why do you think that very small concentrations of BPA mighthave a large effect on the cell?
- Some cancers show increased incidence with age while others peak at younger ages. Whydo you suppose that some cancers have increased incidence with age while others peak inchildren?Retinoblastoma is a rare cancer in which tumors developin the retina of the eye. The tumors arise because of theloss of the Rb gene, which codes for a tumor suppressor.Hereditary retinoblastoma usually appears in children whohave inherited only one functional copy of Rb. Explain whythe nonhereditary form of retinoblastoma usually occurs laterin life.A genetic predisposition to developing cancer is usually inheritedas a dominant trait. At the level of cellular function, are the allelesinvolved actually dominant? Explain why some individuals whohave inherited these dominant alleles do not develop cancer duringtheir lifetimes.
- At the checkpoints of the cell cycle, proteinscalled cyclins bind to________________ and activatereactions that enable the cell to proceed tothe next stage of the cycle.Cancer cells can be characterized as “generic” cells thatperform no specialized body function. Thus cancer cellslack ________.a. differentiationb. reproductionc. responsivenessd. both reproduction and responsivenessWhich of the following would improve an individual's ability to avoid cancer while aging?: a. decreases DNA repair accuracy during mitosisb. makes him smaller (e.g., fewer total cells)c.
