Why do cells copy all the DNA chromosomes before dividing into two new cells?

In order for cells to divide and produce properly working cells, each resulting cell has to contain all the proper DNA. As such, the DNA is replicated so the cells each have the full DNA, so nothing is missing.

Why is it important for a cell to copy its hereditary information before dividing?
why is it important for a cell to copy its heredtiy information before dividing
Are homologous chromosomes found in diploid cells?
Yes, the chromosomes double/make a copy of themselves.
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.
It is important for chromosomes to be copied before cell division because?
DNA must be copied before cell division so that one complete copy of each chromosome ends up in each of the two daughter cells. Otherwise only one cell would end up with DNA, making the other cell.. well.. not a cell.
Why must chromosomes be copied before cells divide?
It ensures that each newcell will be an exactcopy of its parent cell.
Why do cells need to copy their chromosomes before they divide into two daughter cells?
They copy their chromosomes so that when they do divide into two different cells each one will have its own set of chromosomes and it couldn't be copied and transferred after divison occured
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.
How do cell prepare itself before dividing?
It gathers nutrients to make a copy of its DNA

What is a nuclear division in eukaryotic cells in which each cells receive a copy of the original chromosomes?
mieosis.

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.
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.

Why must chromosomes be copied before cells divide?
It ensures that each newcell will be an exactcopy of its parent cell.
Cells must copy their DNA before they do what?
Cells must copy their DNA before they can divide into new cells. Replication (of DNA) before division (of the cell)
Why is DNA copied before mitosis?
DNA has to replicate before mitosis to keep the number of chromosomes and DNA in the cell consistent. Mitosis is the process of reproducing cells by splitting one cell in half to make two. If the DNA didn't replicate, the two daughter cells wouldn't be able to have a complete strand. DNA replicates by dividing in half, then creating a mirror image of itself. Replication gives both strands of DNA an EXACT copy.For instance, say a cell contains 46 chromosomes (a human body cell). Before dividing in half, it has to double its amount of chromosomes. That way, each offspring cell has the same amount of chromosomes that a normal body cell has. If there weren't the same amount of chromosomes inside all of your body cells, you would have a disability. So, the amount doubles to 92 chromosomes. Then, when the cell splits, each of the offspring again have 46 chromosomes. This is because the chromosomes split equally between the two cells. If it didn't duplicate, the number of chromosomes in each cell would decrease by half each time. This would lead to some cells having a small amount of chromosomes and some cells still having 46. If this occurred, the body would not function properly. This is the same concept with DNA. *REMEMBER* Chromosomes replicate along with the DNA before mitosis begins.Hope that this helped! :D
