Two - the leading strand and the lagging strand.
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
DNA replication produces two copies of the DNA.
If you mean reproduction, they reproduce by the process of binary fission. This is analagous to mitosis in the eukaryotes in the sense that the end result is two genetically identical copies of the original bacterium.
The DNA is a double-helix, two strands of nucleotides that are required to pair up in a particular way: adenine to thymine, and guanine to cytosine. During replication, this pairing code is kept perfectly, ensuring that each copy is identical.
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
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 polymerase are enzymes that form bonds between nucleotides during replication.

A cell's DNA is copied during replication.

Identical twins!
