Telomerase
The parent cell had 4 chromosomes as well. During prophase, the cell replicates its DNA, resulting in two identical sister chromatids for each chromosome. So, although visually it appears to have 4 chromosomes, it actually has 2 pairs of sister chromatids.
AnswerThe chromosomes replicates themselves before splitting into two daughter cells.
Telomerase maintains the telomeres of chromosomes in order to prevent cell death. This enzyme added sequences onto the ends of the chromosomes, thereby preventing extreme shortening and loss of genetic material. In a way, telomerase would give cells immortal life, by continuously regenerating its ends. However, telomerase are usually inactive in the human body because normal cells do not divide frequently, and therefore, the chromosomes do not shorten.
One Cell has 10 chromosomes, it divides into 5 chromosomes. So at the end it has, 5 chromosomes. Your Welcome for the answer! ^_^
It will have 18 chromosomes at the end of mitosis.

Chromosomes replicate when DNA replicates during the S phase (synthesis) of of the cell cycle.

The chromosomes must be duplicated. the real answer: DNA replicates and forms tetrads

Chromosomal material replicates during mitosis. Chromosomes become sister chromatids, which ultimately break off to form identical chromosomes and two identical cells.

The daughter cell will have five (5). The parent cell replicates its DNA in a stage of mitosis called Interphase before it splits, into two new daughter cells with the same number of chromosomes.
It will have 18 chromosomes at the end of mitosis.
