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 one of the following cell cycle checkpoints functions to ensure that the chromosomal DNA has been completely copied before the cell proceeds to the next phase of the cycle? a.The restriction point b.The M checkpoint c.The G1 checkpoint d.The G2 checkpoint
Madhur L.
Describe what occurs at the M checkpoint and predict what would happen if the $\mathrm{M}$ checkpoint failed. a. The $\mathrm{M}$ checkpoint checks for proper separation of sister chromatids and if it fails, then cells may undergo nondisjunction of chromosomes. b. The $\mathrm{M}$ checkpoint checks if the DNA is damaged and promotes its repair. If it fails, then the daughters end up with damaged DNA. c. The $\mathrm{M}$ checkpoint ensures the proper duplication of DNA and if it fails, the cells may undergo nondisjunction of chromosomes. d. The $\mathrm{M}$ checkpoint ensures that all the components required for cell division are available and if it fails, the cell cycle will be inhibited.
What is necessary for a cell to pass the G2 checkpoint? a. cell has reached a sufficient size b. an adequate stockpile of nucleotides c. accurate and complete DNA replication d. proper attachment of mitotic spindle fibers to kinetochores
