The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
This is Mitosis, hope this helps =]

If it changed too fast then it would be difficult for the chromosomes to match up and offspring could not be produced. The quality must be maintained or proteins and other systems will not work correctly.

How do the new copies of DNA compare to the original DNA?
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
Why would identical twins produce the same DNA fingerprint?
Identical twins are formed by the human egg splitting after being fertilized. The DNA also splits, and each new egg contains the DNA of the original. This means that the twins, once born, have identical DNA. It's worth nothing that they won't have the same physical fingerprint.
When a DNA molecule is replicated is the second molecule almost identical to the first true or false?
There are quite a few things true about replicated DNA. The most important detail is that replicated DNA is exactly the same as the original copy. When DNA is replicated and the double helix is split, the new bases link with the old ones in the exact same sequence.
When DNA splits a new 'what' of DNA is formed?
A new strand of DNA exactly alike to the original is created.
What is the role of the DNA new strand?
It is a copy of the Dna original strand.
Copy and complete the events chain concept map of DNA synthesis?
step1: enzyme separates DNA sides. step2: new bases pair with bases on original DNA. step3: two new identical DNA molecules are produced.
The exactness of the duplication process in DNA?
It can be assures that new DNA molecules will be identical to the original ones. BY:MARIA J<3

At the end of replication each new DNA molecule is composed of?
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
When a DNA molecule is replicated is the second molecule almost identical to the first true or false?
There are quite a few things true about replicated DNA. The most important detail is that replicated DNA is exactly the same as the original copy. When DNA is replicated and the double helix is split, the new bases link with the old ones in the exact same sequence.
When a DNA molecule replicates are the 2 new strands identical?
Yes, they both are [all but] Identical.
How does DNA in a new cell compare to the old cell when it replicates?
Since replication is semi-conservative and DNA replicates before mitosis the DNA in the new and old cell ( if you wish to use that terminology, as both are daughter cells ) is composed of one new strand and one old template strand.
How does DNA copy it self?
When chromosomes are duplicated before mitosis or meiosis, the amount of DNA in the nucleus is doubled. The Watson and Crick model shows how this takes place. The two sides of DNA unwind and separate. Each side then becomes a pattern on which a new side forms. The new DNA has bases that are identical to those of the original DNA and are in the same order.
Why is DNA copied in the process of replication?
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
Why does each new cell in the body contain an identical series of DNA molecules?
due to DNA replication
When DNA splits a new 'what' of DNA is formed?
A new strand of DNA exactly alike to the original is created.
