Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Later in cell division, the two sister chromatids of each duplicated chromosome separate and move into two new ____
A
nuclei
B
cytoplasms
C
they don’t move
D
None of the above
Explanation: 

Detailed explanation-1: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin-which linked the sister chromatids together during prophase-causes this separation to occur.

Detailed explanation-2: -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-3: -I. G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell.
