Verified step by step guidance1
Understand that mitosis is a process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.
Recall that human cells typically have 46 chromosomes, which are organized into 23 pairs. During mitosis, these chromosomes are duplicated and then divided equally between the two new cells.
During telophase, the final stage of mitosis, the chromosomes have already been separated into two sets, one for each new cell. The nuclear membranes begin to reform around each set of chromosomes.
Each new cell will have the same number of chromosomes as the original cell. Since the original human cell has 46 chromosomes, each new cell will also have 46 chromosomes.
Therefore, during telophase of mitosis, each of the new cells will contain 46 single chromosomes, as they are identical to the parent cell.
