Chapter 9, Problem 4FIB
Summary Introduction
Introduction:
Eukaryotic cells are more complex than prokaryotic ones because they have special organelles. An organism whose cells have a nucleus surrounded by a membrane and whose DNA is in collaboration with proteins is called eukaryotic cell. Checkpoints are control mechanism in cells which ensure proper division of cell.

Scientists are able to isolate cells in various phases of the cell cycle. During an experiment in which Dr. Patrick McGroyn is causing cultured tumor cells to go through mitotic cell division, he isolates a group of cells that contain one and a half times more DNA than cells isolated in the G1 phase have. What phase must these cells be in? How do you know?
Which of the following statments about the cell cycles is correct?
When the S phase of the cell cycle is finished, a cell has twice as many chromatids as the number of chromosomes in the G1 phase
In actively dividing cells, the S and G2 phases are collectively known as interphase
The phases of the cell cycle are G1, S, and M phases
The cell cycle is a sequence of replications and divisions that produces new cells
The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis.
Which of the following describes the consequence of a severe disruption of interphase in cells in healthy tissue?
Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.

- Chemotherapy utilizes chemicals to interrupt various parts of the cell cycle, targeting rapidly growing cells. Taxol® is an example of a drug that prevents mitosis phase from occurring. How this Taxol useful as a cancer treatment and how might targeting rapidly growing cells explain common chemotherapy side effects such as hair loss and nausea? A. Taxol will stop the tumor from growing, but unfortunately it also impacts other fast-growing cells (like hair follicles and stomach lining cells), so normal cells get damaged as well. B. Taxol will stop the tumor from continuing to divide, but unfortunately it also impacts other readily dividing cells (like hair follicles and stomach lining cells), so normal cells get damaged as well. C. Taxol will stop the tumor from copying DNA, but unfortunately it also impacts DNA replication in other cells (like hair follicles and stomach lining cells), so normal cells don't get to continue through…arrow_forwardSometimes a cells "deal with" damaged DNA by just killing off the cell. This special cellular suicide is called apoptosis. Usually, the cell cycle has checkpoints that prevent damaged/mutated cells from proceeding to the next phase, though. When these checkpoints don't work, apoptosis can be used. If apoptosis did NOT occur, how might the damaged DNA impact the rest of the cell cycle? A. it may not complete the cell cycle correctly B. new cells containing damaged DNA may be made C. the cell may enter G0 D. all of the above are options E. A and B, but not C F. B and C, but not Aarrow_forwardNormally functioning cell cycle regulators are molecular signals that do all of the following EXCEPT: Inhibit progression through the cell cycle Stimulate progression through the cell cycle Instruct cells to progress from M phase directly to G2 phase during the cell cycle Instruct cells to initiate programmed cell death during development Instruct cells to differentiate during developmentarrow_forward
