The chromosomes have to split and go to opposite sides of the cell.
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
A bacterium's circular chromosome is copied during a process called DNA replication. This typically occurs before the bacterium divides through binary fission to ensure that each daughter cell receives a complete set of genetic information.
During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.-6th grade science teacher
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.

it triples in number
Your DNA is copied into the new cell every time it divides

A bacterium's circular chromosome is copied during a process called DNA replication. This typically occurs before the bacterium divides through binary fission to ensure that each daughter cell receives a complete set of genetic information.
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.

It is the development and growth that happens after the animal/human is born. (prenatal is before birth, postnatal is after birth)
