Understand the process of mitosis: Mitosis is a type of cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Recall the stages of mitosis: Mitosis consists of several stages, including prophase, metaphase, anaphase, and telophase. During anaphase, the sister chromatids are separated and pulled to opposite poles of the cell.
Consider the chromosome number before cytokinesis: After anaphase, each chromatid is considered a separate chromosome. Therefore, the number of chromosomes doubles temporarily.
Apply this to human cells: A typical human cell has 46 chromosomes. After the sister chromatids separate during anaphase, there are 92 chromosomes present in the cell.
Recognize the timing: Before cytokinesis, the cell has not yet divided into two separate cells, so it temporarily contains 92 chromosomes, which will be distributed equally into the two daughter cells during cytokinesis.
