Question 16 0.5 pts The cell cycle has many check-points to ensure the cell is ready for division. Which of the following can occur if a cell skips cell cycle checkpoints O the cell can have inhibited growth O the cell can divide into three daughter cells instead of two O the cell can grow in size, but never divide O none of these can occur O the cell can become cancerous

During the cell cycle, the cell must pass through several checkpoints that confirm that the cell is ready to progress to the next phase of the cycle. If the requirements of one phase have not been met, the cell cannot proceed to the next phase. These checkpoints help control the rate of cell division. If a mutation disables one of these checkpoints, what is most likely to happen? a. Cells proceed through phases of the cell cycle in the wrong order b. Cells remain in one phase of the cell cycle for the rest of their existence c. The cell begins dividing too often, forming a tumor d. Cells divide slowly, reducing organ function.

When normal human cells are grown in a culture plate, they typically stop growing once a monolayer of cells is formed at the bottom of the plate. This arrest in division is an example of: Anchorage-dependence cell division Growth factor-induced division Density-dependent inhibition Malfunction of the cell cycle checkpoints When a DNA segment is cut and inserted in the opposite orientation, it is an example of: Deletion Inversion Reciprocal translocation Duplication
