How can defects in the regulation of cell-cyle checkpoints would affect cells and explain how these defects relate to uncontrolled division in cancer and cancer progression? Describe the movements of chromosomes and the status of the microtubules spindle during interphase, prophase, metaphase, anaphase, and telophase? Explain the movement of chromosomes during stages of meoisis to produce sperm and eggs?

Which of the following is NOT a checkpoint that controls the progression of cell cycle? The metaphase checkpoint determines if all chromosomes are attached to the spindle apparatus Cytokinesis involves the formation of cleavage furrow to separate the cells The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated Cyclins and cyclin dependent kinases are protejns that are responsible for advancing a cell through the phases of the cell cycle

Progression through the cell cycle is dependent on both extra- and intracellular conditions. Consider the following conditions. Indicate which checkpoint (s) responds to that condition.a. The cell is large enough to divide.b. The DNA is completely copied during S phase.c. The cell is receiving positive cues from neighbors.d. The DNA is damaged.e. The cell has enough energy reserves to divide.f. Are all the sister chromatids correctly attached to spindle microtubules?
