PLEASE HELP QUICK, 100 POINTS AND BRAINLIST. 1) A model of the cell cycle with checkpoints, cyclins, and CDK molecules is shown. Cyclins and CDKs are molecules that regulate the cell cycle. Checkpoints are specific portions of the cell cycle when the cell ensures proper growth, replication, and chromosome alignment before dividing. A cancer cell isolated from a tumor is found to have an improper number of chromosomes. Which scenario described below most likely results in a cancer cell with an improper number of chromosomes? A) The cancer cell ignored the G1 checkpoint. B) The cancer cell ignored the M checkpoint during mitosis. C) The cancer cell had excessive levels of cyclin E and CDK 2. D) The cancer cell had inadequate levels of CDK 1 and cyclin B.
