Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What happens to the chromosomes during anaphase?
A
they line up
B
they are pulled apart
C
they are at either end of the cell
D
they duplicate
Explanation: 

Detailed explanation-1: -During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.

Detailed explanation-2: -Cytokinesis: Cytokinesis is the final stage of the cell cycle; it can occur anywhere from Anaphase into Telephase once the chromosomes have separated. The cytoplasm of the cell begins to split. It divides roughly in half. These two halves are identical copies of one another.

Detailed explanation-3: -In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein “glue” that holds the sister chromatids together is broken down, allowing them to separate. Each is now its own chromosome. The chromosomes of each pair are pulled towards opposite ends of the cell.
