Textbook Question
Chapter 20, Problem 12P
One of the hallmarks of mitotic anaphase is the separation of sister chromatids. A protein complex called cohesin holds sister chromatids together, as described in Fig. 12.25. Based on the answer you have just given for Problem 11, propose a mechanism that would allow sister chromatids to separate during anaphase. How might your proposed mechanism also explain the checkpoint operating in M phase that prevents sister chromatid separation until all the chromosomes have connected properly to the mitotic spindle?

Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard vision test. The results were analyzed and graphed (See Figure…arrow_forward
