During replication the double helix is unwound and the DNA strands are separated. An enzimatic machinery (polymerase) synthesizes the complement to that strand. So, if you start with 1 double helix (2 strands), in the end you will have a copy of the double helix, plus the original. (4 strands.)
The purpose of replication is to replace dammaged, broken or misarranged DNA in your cells. Since DNA encodes all the proteins in your body, a cell constantly needs to replicate it's own DNA to make new cells and proofread the current DNA that's already there.

During DNA Replication, the DNA is replicated. This means that an enzyme goes down the strand of DNA and takes everything on one side to the new DNA. Then, everything that is missing is then put back together. Notice, that it is DNA Replication. Replication means that you are copying something. it is like putting something on a copy machine, the more you copy it, the more distorted it gets. Duplication is when you can copy something exactly.
Hope this has helped you!
