Answer:
The mitotic microtubules (MTs) are classified into three major types: kinetochore, interpolar and astral mitotic microtubules (MTs). The MTs play a critical function: they attach to chromosomes by the kinetochores.
The kinetochore is the most stable type of these MTs, while astral and interpolar appear to be more labile. In regard to their differences, it is also important to have into consideration their localization: kinetochores are anchored to the kinetochore, astral are extended from the cell cortex, while interpolar MTs are arranged from the opposite sides in the mitotic spindle.
