Hydrogen bonds between adjacent strands (A-T = 2 H-bonds and C-G = 3 H-bonds)
Base stacking among nitrogenous bases of the same strand
The nitrogen bases in DNA are adenine, guanine, cytosine, and thymine. They pair with each other as follows: adenine pairs with thymine, and cytosine pairs with guanine. The nitrogen bases in RNA are adenine, guanine, cytosine, and uracil. They pair with each other as follows: adenine pairs with uracil, and cytosine pairs with guanine.
Your answer is "Helicase". This is the enzyme responsible for the unzipping of the DNA molecule, or in other words, the breakage of the bonds of its nitrogen bases.
between the nitrogen bases of the two strands of DNA
the hydrogen bonds btw nitrogenous bases leads to stability of the double helix
Adenine, Guamine, Thymine and Cytosine
Describe how each of the DNA nitrogen bases pair together
The two chains are connected by hydrogen bonding between nitrogen bases to form a long double-stranded molecule.So hydrogen bonding determines which nitrogen bases form pairs of DNA.
simple adenine pairs with thymine and guanine pair with cystosine.
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
The 4 Nitrogen Bases are Adenine, Guanine, Cytosine and Thymine
Guanine and Cytosine pair with each other and Adenine and Thymine pair with each other.
This is the process of DNA replication. A DNA strand in the nucleus of a cell, starts off by being "unzipped" by helicase (an enzyme). Then another enzyme, DNA polymerase matches the nitrogen bases (which are freely floating in the nucleus), of each half with their matches, this forms two identical strands, of DNA.
When a nitrogen bases floating in the nucleus ipair up with the basis on each half of the DNA molecule. Remember that the pairing of bases follows definite rules: A always pairs with T, while G always pairs with C. Once the two new bases are attached, two new DNA are formed.

The rungs of DNA are made up of the nitrogenous bases Adenine (A), Cytosine (C), Guanine (G) and Thymine (T). Each rung represents the bonding of two bases (one from each DNA strand). A binds with T and C binds with G.
