Because otherwise you'd have half the information in one of the daughter nuclei and the other half in the other daughter nucleus.
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.
Your DNA is copied into the new cell every time it divides
The nucleus is an important cell part, so if it separates ,it needs to copy information or else the nucleus will become useless.
The structure of DNA allows two functions to occur
A bacterium's circular chromosome is copied during a process called DNA replication. This typically occurs before the bacterium divides through binary fission to ensure that each daughter cell receives a complete set of genetic information.
Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
Before a protein is made, a section of the DNA is copied into messenger RNA (mRNA) through a process called transcription. During transcription, the DNA sequence of a gene is transcribed into a complementary RNA sequence. This mRNA then carries the genetic information from the nucleus to the ribosome, where it is translated into a protein.
DNA is copied in the cell nucleus. This process is called DNA replication and occurs during the S phase of the cell cycle.
the nucleus stores all the genetic information (DNA)
Mitotic division is the includes division of nucleus and it divides the cell into two daughter cell whereas the prokaryotic cell don't have nucleus and they are divided through the process of binary fission
DNA is copied in the cell nucleus during a process called DNA replication. This process involves the separation of the DNA strands, the synthesis of new complementary strands, and the formation of two identical copies of the original DNA molecule.
Because when a cell divides it creates something like a mirror image and to do this it needs to copy the most important part of the cell the nucleus (which holds the DNA) and that will determine what the cell needs to do.
