-Describe what takes place in the three phases of interphase. G1 phase cell growth, S phase DNA synthesis, G2 phase cell growth. -What are cell cycle checkpoints? To pause the cycle at certain transition points. Where are they found in the cell cycle? What do they check for? If DNA is damaged the cycle must be put on hold so the cell can repair the damaged disdis-How do Rb and p53 negatively regulate the cell cycle in G1? -Describe the events that occur in the initiation and elongation of DNA replication in S phase ( Be specific!)

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
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?
BPA 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: How might BPA interact with the cell cycle and its checkpoints?
