Hydrogen bonds
There are two single strands which are found in the DNA molecule. Each of strand will act as the template for the next one in the double helix molecule.
hydrogen bonds between nucleotide bases
I assume you mean the hydrogen bonding that holds bases of DNA together.
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
