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.

∙ 6y agothe 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.

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 ensures that each new eukaryotic cell receives a copy of each chromosome?
Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
What phase is a copy of each chromosome made?
Genetic Information is copied during Cell Division known as Mitosis. This occurs at the stage of Interphase in which the cell grows and prepares for division.
Why is it important for a cell to have two copies of DNA before it enters the division phase mitosis?
It is important for a cell to have two copies of DNA before it enters the division phase of mitosis because each new cell will require a copy of the DNA. The copies are shared between the divided cells.
Why is it important that a cell copy its DNA before mitosis takes place?
This ensures that a cell about to divide has two sets of genetic information , one for each daughter cell.
What happens to DNA before cell division in mitosis?
No, transcription is the process of creating an mRNA copy of the DNA in order to create a function process (by translation at the ribosomes). However, DNA does replicate before mitosis occurs - this is so that each daughter cell at the end of mitosis ends up with the same number of chromosomes as the original cell.
Does mitosis ensure that each new eukaryote cell receives a copy of each chromosome?
Yes, it does! This occurs during G2 phase of Mitosis.

Mitosis results in two identical cells being produced from the original cell. A copy of each chromosome is made before the cell divides and one of each chromosome goes to each new cell.
How does mitosis ensure that a new plant cell is identical to its parents?
Mitosis ensure that a new cell is identical to its parents by their copy of the parent's genome in mitosis. Identical genetic information will result in identical cells.
Why must a cell copy its chromosomes before it can go through mitosis?
When a cell copies its DNA, each chromosome must be copied.
Does DNA replication occur before the division of the nucleus in both meiosis and mitosis?
The cell cycle consists of interphase followed by cell division (in this case mitosis). it's true that DNA replication occurs during interphase, however interphase itself has 3 phases: 1. G1(=gap1): when the cell grows and fuctions 2. S (=Synthesis) when DNA replication occurs (as synthesizing anew DNA copy) 3. G2 (gap2): when the cell accumulates nutrients before the division itself.
What phase is a copy of each chromosome made?
Genetic Information is copied during Cell Division known as Mitosis. This occurs at the stage of Interphase in which the cell grows and prepares for division.
Do chromosomes double in mitosis?
Mitosis occurs in almost all eukaryotic cells. The duplication of chromosomes only occurs during the S phase of interphase in mitosis to form chromatids.
Why is it important for a cell to have two copies of DNA before it enters the division phase mitosis?
It is important for a cell to have two copies of DNA before it enters the division phase of mitosis because each new cell will require a copy of the DNA. The copies are shared between the divided cells.
How does mitosis ensure that a cell is identical to its parent cell?
Mitosis ensure that a new cell is identical to its parents by their copy of the parent's genome in mitosis. Identical genetic information will result in identical cells.
What makes copies of themselves before mitosis?
The chromosomes are copied, so that each daughter cell has an exact copy of the genetic material.
