Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the difference between metaphase and anaphase?
A
Metaphase is after anaphase
B
Anaphase has chromosomes lining up and metaphase has them split apart
C
Metaphase has chromosomes lining up and anaphase has them split apart
D
Anaphase is after metaphase
Explanation: 

Detailed explanation-1: -In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.

Detailed explanation-2: -In metaphase, chromosomes are aligned on the spindle with sister kinetochores facing toward the opposite poles. In anaphase A, sister chromatids separate from each other without spindle extension, whereas spindle elongation takes place during anaphase B.

Detailed explanation-3: -The cleavage of the centromere is taken place in Anaphase of Mitosis, whereas it does not occur in Anaphase I of meiosis.

Detailed explanation-4: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly-freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.
