DNA replicates before a cell divides ensures that each daughter cell has a complete set of genetic material They must have an identical set of DNA.
Then it would not have enough copies of chromosomes to give the right amount to the daughter cells. This may result in half the daughter cells receiving the DNA and half receiving no DNA - or else...
DNA is not a cell.
Half from one, half from the other
DNA determines what characteristics the cell would have. When a cell divides, the chromosomes containing DNA are split in half. Half of the DNA from the original cell is carried by each of the resulting cells.
The exact amount of chromosomes as the mother cell, depending on which process the cell is dividing.
If DNA replication did not occur, then when the cell divides the amount of DNA available would be divided. Half going into the knew cell the other half remaining in the parent cell. Each cell would then contain only half the number of chromosomes that it should have and would die fairly quickly.
be half that of the original cell.
The DNA content of each cell produced after meiosis I would be haploid, which means it would be half of the DNA content present in the original cell during the G2 phase. This is because meiosis I halves the number of chromosomes in the cell.
During mitosis, during the division of the nucleus, the double helix of the DNA unwinds. After the cells divide, each half of the DNA goes to each new cell, and then the other half is reconstructed based on the type of proteins present in the DNA.
The cubs of the two different parents have different DNA because they are made up of half the DNA from the papa bear, who gives a sperm cell, which is haploid. That means it only has half of the DNA to form a cub. The other half comes from the egg of the mama bear, which is also a haploid cell. The sperm and the egg come together and form a diploid cell. That is the whole DNA for a bear cub.
Meiosis.

The cell is most likely in the G1 phase of the cell cycle. During G1 phase, the cell prepares for DNA replication in the S phase. Cells with half the amount of DNA compared to others have likely already undergone DNA replication and are in the early stages of the cell cycle.
