Which of the following is NOT a checkpoint that controls the progression of the cell cycle? Cyclins and cyclin-dependent kinases are proteins that are responsible for advancing a cell through the phases of the cell cycle. The G2 checkpoint checks for DNA damage and determines if all of the DNA is replicated. 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 restriction point determines if conditions are favorable for cell division and if the DNA is undamaged.

Which checkpoint is primarily responsible for assessing whether DNA has been completely duplicated (replicated)? A. G1 checkpoint B. G2 checkpoint C. M checkpoint D. all of the above Anaphase of mitosis can best be described as: A. pulling apart sister chromatids so that daughter cells are genetically identical B. pulling apart homologous chromosomes so that daughter cells are genetically unique C. pulling apart sister chromatids so that daughter cells are genetically unique D. pulling apart homologous chromosomes so that daughter cells are genetically identical

Which of the following occurs during the G1 phase of the cell cycle? the G1/S checkpoint is reached at the end of the G1 phase the cell completes preparation for replication of DNA the cell grows the cell synthesizes various enzymes that are needed later on for DNA replication all of these answers are correct
