What two types of movement are responsible for separating sister chromatids during anaphase?

Two types of movement are responsible for separating sister chromatids during anaphase.
Kinetochore Microtubules attach to the chromosomes and are responsible for separating the chromosomes during anaphase.
NonKinetochore Microtubules from the two centrosomes overlap in the middle of the cell and are responsible for elongating the cell during anaphase.
