Challenge:

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

At the end of cytokinesis, how many chromatids will be found in each daughter cell? Explain.

The answer is 46 chromosomes.
Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.

At the end of cytokinesis, each daughter cell will have 46 chromatids. This is because, during mitosis, the sister chromatids split and are distributed evenly to each daughter cell. After the division, each daughter cell retains a complete set of chromosomes, which totals to 46 chromatids in each cell.
