I think the nucleus is the best answer.
If the DNA is not duplicated, then only one cell would have DNA, and a cell cannot live without DNA.
DNA replication
A circular band of DNA that exists separate of chromosomal DNA is called a plasmid. Plasmids reside within bacteria cells and can replicate independently of the chromosomal DNA.
true...
It is also called The Chromosomal Material, or Substance.
nucleus
Synthesis of Interphase, before the Mitotic Phase in the cell cycle.
Chromosomes duplicate in a process called mitosis.
A plasmid is an extra chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently from the chromosomal DNA http://en.wikipedia.org/wiki/Plasmid I think this is far use.
+other than chromosomal DNA is known as extra chromosomal DNA like plasmids, mitochondria and chloroplast containing DNA.
If the DNA is not duplicated, then only one cell would have DNA, and a cell cannot live without DNA.
It becomes duplicated.
DNA replication
DNA replication
DNA is replicated in the process called Mitosis and Meosis. DNA is replicated to make more cells. Your body will make cells if you have a cut, grow, etc..
Duplicated nuclear material is called chromatin.
