DNA replication
replication
DNA replication is the process by which a cell duplicates its DNA. It occurs during the S phase of the cell cycle and involves the separation of the DNA double helix, the synthesis of new complementary strands, and the proofreading and correction of errors to ensure accurate duplication.
DNA is in the nucleus of a cell. When a cell divides (mitosis) the DNA in the nucleus must first duplicate. Basically an identical copy of the cells DNA is made. This creates another nucleus in the cell with a copy of the DNA. The cell it's self then divides, separating the 2 nuclei. Each cell having one each.
The DNA is synthesized during the S-phase of the cell's Interphase (G1, S, G2)... That is why it is called the "S" phase-- standing for the word "synthesis".
The stage in the cell cycle when DNA is copied is the S phase of the interphase. It refers to the resting phase between successive mitotic divisions of a cell.

its called cloning
When a cell duplicates, both the DNA and the chromosomes duplicate.

In the beginning of the eukaryotic cell cycle, the cell undergoes a phase called G1, where it grows and carries out normal functions. During this phase, the cell also duplicates its organelles and prepares for DNA replication in the subsequent phases.
DNA duplicates during the S phase of the cell cycle, which occurs before cell division in the interphase stage.
