b. In the space below, develop a handout or diagram to explain how these checkpoints work under normal conditions. Your diagram should include a description of each checkpoint, where it acts in the cell cycle, and what each does to control cell division.

hello I'm asking for question 1B I already answered 1A & 1C

NameMuroaRoa Moreno Course/Section. Date Professor/TA Activity 18.4 What controls the cell cycle? 1. Checkpoints in the normal cell cycle prevent cells from going through division if problems occur-for example, if the DNA is damaged. a. What forms do the checkpoints take? That is, how do they control whether or not cell division occurs? Amimber of different cyclins are produced during interphase. 3 ofthe major checkpoints in mitosis-the G,G, & Mphase cneciepoints-cppear to bé contro1led by Caks (cyclin-deperdent Kinases).The ratio of cdks t their CyClins determines their activity The activities of tne different activated CdKs controlthe cell aycle, The cell can move past given'stage of theeycle only when the agproprate cneckpoints cdk nas boenactivated. b. In the space below, develop a handout or diagram to explain how these checkpoints work under normal conditions. Your diagram should include a description of each checkpoint, where it acts in the cell cycle, and what each does to control cell division. c. Cancer results from uncontrolled cell division. Explain how mutations in one or more of the checkpoints might lead to cancer. The basic function of each aneckpoint is to determine wnether or not the cele is functioning normaluy &snould enter intor continue through diision. If tnese checkpoirits break oloun , they could allow any cell to Continue the cell cycle -that is, to diide Cancer is uncontrolled cell division,so caner can result fronma through breakdouun of the operation of trese checkpoints.
