Sort the events of centriole activity during cell division in the correct sequence.

(1) Both pairs of centrioles are located just outside the nucleus during interphase

(2) Mitosis begins and centriole pairs move apart

(3) Microtubules radiate around each centriole forming asters

(4) The spindle forms and chromosomes align along it

(5) Centrioles replicate during telophase so each daughter cell has a pair

Explanation

Centriole activity through cell division:

1. Interphase - both pairs of centrioles sit just outside the nucleus, arranged at right angles to each other
2. Mitosis begins - centriole pairs move apart toward opposite poles
3. Asters form - microtubules radiate from each centriole
4. Spindle assembles - microtubules extend pole to pole; chromosomes align at the equator
5. Telophase - centrioles replicate so each daughter cell receives its own pair
