These two amounts are Equal.
Interphase is when DNA replication occurs. :)

In late anaphase and G1 of interphase, a chromosome is unreplicated and consists of a single DNA double helix. A replicated chromosome contains two identical DNA double helices.
DNA and Protein
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
The region of a chromosome holding the two double strands of replicated DNA together is called a centromere. The complex of DNA and protein that makes up eukaryotic chromosome is properly called chromatin.

There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
Many viruses can infiltrate a host's DNA to replicate itself. An example of this is the AIDS virus.
There is twice as much DNA in a chromosome that has replicated than there was before replication.The amount will be halved again at anaphase of the subsequent mitosis (or meiosis II), when the two halves (chromatids) of the chromosome separate, and each half is from then on referred to as a daughter chromosome.
In bacterial Cells they become replicated circles of Dna. In eukaryotic Cells they become Chromosome number 4n.
