I have read in a textbook of Arihant that besides shortening of kinetochore microtubules, it is the lengthening of non-kinetochore microtubules, which is also responsible for the separation of chromosomes. Can you please please explain these???

Dear student
Their are some microtubules which are attached to the kinetochore protein of the chromosome. There are also non kinetochore microtubules which are not attached to the kinetochore. Microtubules are made of protein which can polymerise and lead to lengthening. When they depolymerise they cause shortening.
Separating the sister chromatid is possible when the kinetochore microtubules depolymerise and shorten and at THE SAME TIME MICROTUBULES NOT ATTACHED TO CHROMOSOME LENGTHEN PUSHING THE TWO POLES/CENTRIOLES FARTHER APART AND ELONGATING THE CELL
