Why is it important that the chromosomes make exact copies of themselves before the divides?

It's because, we need to divide the cells equally with the same DNA. If chromosomes aren't copied exactly, your body parts may not be able to function the way it usually does. Sometime it could be a serious problem, otherwise, you might just get an extra toe, or something else that doesn't harm you internally.

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.
Why do chromosomes line up in the middle of the cell during metaphase?
It is important that chromosomes move during mitosis because the chromosomes' sister chromatids need to separate. They must separate to become daughter cell-carrying chromosomes themselves.
Before a cell divides it must first make an exact copy of all of its?
A cell must make an exact copy of its genome before it divides. Genomes are the complete set of chromosomes present in a cell.
When a cell divides by mitosis how is the chromosome number affected?
In the beginning of mitosis the number of chromosomes double. But since during mitosis the chromosomes are divided between the two daughter cells the number of chromosomes at the end is the same number as the beginning before doubling.
Why do chromosomes in parent cell duplicate during mitosis?
Chromosomes doubles during the S phase of inter-phase, which occurs before Mitosis. During the process of mitoses cell divides into 2 daughter cells from a single parent hence, before mitoses cells must duplicate so that each new cell has a sufficient set of genetic material.

When a body cell divides through the process of mitosis what is the number of chromosomes in the daughter cells?
After mitosis each daughter cell contains 46 chromosomes as the DNA replicates itself before the cell divides

What happens to the chromosome before an animal cell divides?
The chromosomes have to split and go to opposite sides of the cell.
Why does a cell make a copy of itself before it divides?
So that the new cells have the same chromosomes as the parent cells.
Before a cell divides it must first make an exact copy of all of its?
A cell must make an exact copy of its genome before it divides. Genomes are the complete set of chromosomes present in a cell.
How many chromosomes are in a human cell before and after meiosis?
When meiosis begins at Gap 1 phase (G1) the cell of a human has 46 chromosomes or 2n.
During binary fission of prokaryotes both the original and the duplicated chromosomes attach to what before the cell divides in half?
plasma membrane; :)

If the original cell has 46 chromosomes how can each daughter cell also have 46 chromosomes?
AnswerThe chromosomes replicates themselves before splitting into two daughter cells.
What happens to genes when cells divide?
If a cell divides by mitosis both cells will have the diploid (2N) number of chromosomes. These two cells will have identical DNA If a cell divides by meiosis subsequent cells will have the haploid (1N) number of chromosomes. These cells will have the same basic amount of DNA but the DNA will not be identical. If the sex chromosomes are different sizes (like the X and Y chromosomes of humans) the DNA will vary a bit more dramatically if the meiosis includes the additional variation of the different sex chromosomes.
