Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During this phase, replicated chromosomes move towards the center of the spindle as the spindle forms:
A
Prophase II
B
Prometaphase II
C
Metaphase II
D
Anaphase II
Explanation: 

Detailed explanation-1: -Metaphase follows prophase. During metaphase, the chromosomes align in the center of the cell at the equatorial plate and the spindle fibers attach to the centromeres of the chromosomes.

Detailed explanation-2: -In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the midpoint of the cells in metaphase II. In anaphase II, the sister chromatids are separated.

Detailed explanation-3: -Prometaphase I The nuclear membrane disappears. One kinetochore forms per chromosome rather than one per chromatid, and the chromosomes attached to spindle fibers begin to move.

Detailed explanation-4: -Anaphase II: The chromatids split at the centromere and migrate along the spindle fibers to opposite poles.
