While I have learned about the cell cycle many times in high school as well as college, I never realized how complex this cycle truly is. I was aware of checkpoints and the steps, but there are so many different "switches," mechanisms, and regulations to make sure cells going through replication come out normal. It amazes me that even though the cycle is so complex, for the most part, our cells and we come out fairly normal and function properly. I guess the many regulations prevent errors from occurring, but it still is amazing! I wasn’t sure what nucleating microtubules was or its purpose, so I looked it up. Microtubules nucleation is the process in which tubulin alpha-beta heterodimers begin aggregation to form an oligomeric tubulin structure, also known as a microtubule seed. The microtubule seed then eventually forms into a microtubule. This means that microtubule nucleation is the initiating step in the formation of a microtubule when there are no microtubules present.
