DNA is not copied during mitosis. It is copied in the portion of the cell cycle prior to mitosis during the S phase of interphase and is called DNA Replication.

What happens to DNA during the S stage of interphase?
interphase is oneof the longest phases of mitosis. during interphase the DNA replicates
DNA replication occurs in preparation for what?
Both mitosis and meiosis
Is DNA copied exactly when new chromosomes form during mitosis?
The DNA sequence of the cell is not supposed to change during mitosis. There are actually "proof reading" and corrective enzymes to check for errors and correct them. However, sometimes a change does occur, and that change is called a mutation. Depending on which gene is affected, a mutation can have no effect or a devastating, life threatening effect, such as cancer.
During replication, DNA?
adenine bonds with thymine The bases on these nucleotides are very particular about what they connect to. Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code.
What is the process by which a DNA molecule is copied called?
dna replication. can be summarised as the two helical strands of dna unravelling through the action of enzymes and the corresponding nitrogenous bases of each being matched up (A-T, C-G) to form two identical strands
Can DNA be copied in mitosis?
DNA is not copied during mitosis . Mitosis is meant for division of cell and DNA is divided in two daughter cells .
What happens to DNA during the S stage of interphase?
interphase is oneof the longest phases of mitosis. during interphase the DNA replicates
When and where is DNA copied and separated?
Mitosis
What is copied before mitosis begins?
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.
What is copied during mitosis and meiosis?
A cell and its chromasomes.
What diagram models replication in which DNA is copied before mitosis occurs?
DNA duplication diagrams
DNA replication occurs in preparation for what?
Both mitosis and meiosis
In mitosis how many times is the DNA copied?
In both mitosis and meiosis DNA replication only occurs once, during Interphase and Interphase 1, for mitosis and meiosis, respectively.
When do chromosomes (DNA) replicate?
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
