Chromatin condensation and movement of duplicated centriole towards opposite pole can be observed during-
Options:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Dear Student

Correct option is (1).
Chromatin condensation begins during prophase and chromosomes become visible. 
Also, the spindle also begins to form as the two pairs of centrioles move to opposite poles and microtubules begin to polymerize from the duplicated centrosomes.
