For those curious, it is now understood how the kinetochore microtubules "pull" the sister chromatids: the kinetochores depolymerize the microtubules, which results in the breakdown of the microtubule into tubulin subunits. This effectively shrinks the microtubule, resulting in the chromatids moving towards the centrosome.

Incredible! This should be pinned. It's amazing how almost everything at that level operates by this sort of electromagnetic gravity from the molecular bonds. It blows my mind how many complex processes such a simple force can perform.

An easy why to remember the name of the stages is the acronym IPMAT, which stands for, "I Pull Me A Twin." And it actually makes sense... to a certain extent (Interphase, Prophase, Metaphase, Anaphase and finally Telophase). Hopes this helps! Aleksi.

I've noticed in biology, you can memorize the terms, but if you just use flash cards, etc it's not the same as actually UNDERSTANDING the material and how everything works together. If you don't, tests will always get you with a technicality. Example: Centromere, centriole, centrosome. I learned all this material in 20 minutes! Thank you so much!!
