the cell makes a copy of its DNA before starting mitosis because, as organisms grow and change, they need new cells to make more skin tissue, bone tissue, muscle tissue. These new cells can only come from one place other cells- through the process of cell division, or mitosis.
- For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, to repair and replace cells worn out and used up by everyday life, and in some cases, to make specialized cells for reproduction.
So each cells have the same DNA but half the organelles that one cell have.
Add: DNA replication results in two identical copies of each chromosome. There needs to be two copies of each chromosome so that at the end of mitosis each daughter cell has the exact same number and types of chromosomes as the original cell. In other words, the daughter cells must have the exact same DNA as the original cell.

What do chromosomes do before mitosis?
Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
What must a cell do before a cell divides?
It must make a copy of its deoxyribonucleic acid (DNA).
Why does a cell make a copy of DNA before mitosis occurs?
DNA replication results in two identical copies of each chromosome. There needs to be two copies of each chromosome so that at the end of mitosis each daughter cell has the exact same number and types of chromosomes as the original cell. In other words, the daughter cells must have the exact same DNA as the original cell so that each cell has the instructions for carrying out cellular functions.
If a cell has 12 chromosomes how many chromosomes will each daughter cell have after mitosis?
Each daughter cell will also have 12 chromosomes after mitosis. Mitosis is a process of cell division where the genetic material is replicated and divided equally between the daughter cells, maintaining the same number of chromosomes as the parent cell.
How does the genetic make up of cells that results from mitosis differ from the parent cell?
The genetic make-up of cells resulting from mitosis is identical to the parent cell. Mitosis is a process of cell division where the chromosomes in the parent cell are replicated and evenly distributed into two daughter cells, ensuring that each cell receives an exact copy of the genetic material.
How does DNA make the copy exactly the same as the original?
Yes. The cells go through mitosis, where the DNA doubles its chromosomes and eventually separate, giving an exact copy as the cell before.
Does mitosis have the same chromosome number as the parent cell?
yes. the chromosomes make an exact copy of themselves to give to the daughter cell. as the cell starts to split, the copy moves into the daughter cell.

What must a cell do before it can divide to a new cell?
It must make a copy of its deoxyribonucleic acid (DNA).
What does DNA replication make?
DNA replication produces a copy of the DNA. At the same time the cell in which the DNA is to be found splits into two with a copy of the DNA in each. DNA replication is caused by cell replication during the process of mitosis.
If a cell has 12 chromosomes how many chromosomes will each daughter cell have after mitosis?
Each daughter cell will also have 12 chromosomes after mitosis. Mitosis is a process of cell division where the genetic material is replicated and divided equally between the daughter cells, maintaining the same number of chromosomes as the parent cell.
What organelles make up mitosis?
The centrioles are important for cell division (mitosis)
How does the genetic make up of cells that results from mitosis differ from the parent cell?
The genetic make-up of cells resulting from mitosis is identical to the parent cell. Mitosis is a process of cell division where the chromosomes in the parent cell are replicated and evenly distributed into two daughter cells, ensuring that each cell receives an exact copy of the genetic material.
What would happen if a cell did not make a copy of its DNA (its chromosomes) before it divided?
jiii
How can one cell make copies of itself?
Cell Division or Mitosis
