During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.
Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.

∙ 11y agoAfter the chromosome replication cycle is complete, the first duty the Cell Nucleus must perform before Cell Division is to dissolve [amazingly only temporarily] the Nuclear Envelope.
After Chromosome Segregation and Translocation takes place Daughter Cells are formed; and the Nuclear Envelope, with its multi-segmented Nuclear Pores, magically reappears - times two!

However, if you're referring to what happens before mitosis, then it is interphase.
In interphase, the genetic info duplications.

What molecules must pass between nucleus and cytoplasm?
DNA
Why must you go through the process of changing DNA into rna?
In order to protect the DNA from potentially damaging reactions in the cytoplasm, the nucleus prevents the DNA from leaving it. Therefore it must be transcribed by mRNA, which can leave the nucleus.
Why must the nucleus of the unfertilized egg be destroyed before the parent cell's nucleus is inserted?
because the genetic material from the egg's nucleus must be eliminated
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)
MRNA must pass through which membrane?
The nuclear membrane.In eukaryotic cells, DNA is transcribed into mRNA within the nucleus. Once transcription is complete the mRNA must exit the nucleus to be translated into protein, which ocurrs in the cytoplasm. Thus, mRNA must pass through the nuclear membrane.
List five organelles that must divide or fragment before the cytoplasm divides?
Mitochondria, nucleus, Golgi apparatus, ribosome, vacuole.
What molecules must pass between nucleus and cytoplasm?
DNA
In a cell information that controls the production of proteins must pass from the nucleus to the?
The information that controls the production of proteins must pass from the nucleus into the cytoplasm in the form of mRNA. mRNA is a template copy of the DNA inside the nucleus and is read by ribosomes in the cytoplasm to produce proteins.
Why doesnt mitosis alone produce daughter cells?
Mitosis alone does not produce daughter cells because the cytoplasm has to divide. This is called cytokinesis and it happens at the end of telophase.
What are 2 characteristics that that all organisms share?
All cells have to have two characteristics including the ability to grow. Cells must also have the ability to divide.

Kind of a cell that does not have a nucleus?

Why must chromosomes be copied before cells divide?
It ensures that each newcell will be an exactcopy of its parent cell.
Where does RNA editing occur in the cell?
mRNA processing occurs in the nucleus itself. This is because the mRNA processing involves adding the 5' cap and the poly-A tail. These features must be done before the mRNA is released into the cytoplasm because they help prevent it from being digested and harmed by the cell's own enzymes.
