For mitosis and meiosis
DNA replication begins in areas of DNA molecules are called origins of replication.
Prokaryotic DNA replication has a single origin of replication, leading to two replication forks. In contrast, eukaryotic DNA replication has multiple origins of replication, resulting in multiple replication forks forming along the DNA molecule.

Replication of DNA
Nitrogen is used for DNA replication, so you need it for cell replication and growth.
DNA is copied during a process called DNA replication. This process occurs in the nucleus of a cell and involves making an exact copy of the original DNA molecule. DNA replication is essential for cell division and passing genetic information from one generation to the next.
DNA replication produces a copy of the DNA. At the same time the cell in which the DNA is to be found splits into two with a copy of the DNA in each. DNA replication is caused by cell replication during the process of mitosis.
Transcription.
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.
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.
DNA polymerase adds nucleotides to the growing DNA strand at the replication fork during the process of DNA replication.
The site of DNA replication in eukaryotes is the nucleus. Replication occurs in the nucleus because this is where the DNA is stored. The process involves unwinding the DNA double helix and synthesizing new strands of DNA using the existing strands as templates.
