adenine.
If you shear DNA, the bonds that are broken are hydrogen bonds. These are the bonds that reside in between base pairs.

adenine bonds to thymine and guanine bonds to cytosine
DNA base pairs are held together by Hydrogen Bonds. Adenine and Thymine have 2 bonds that hold them together while Cysteine and Guanine have 3 bonds that hold them together. The hydrogen bonds generally occur between a Nitrogen and a carbonyl oxygen.
Guanine pairs with cytosine

If you shear DNA, the bonds that are broken are hydrogen bonds. These are the bonds that reside in between base pairs.
So essentially the difference is that in DNA-DNA base pairs thymine bonds with adenine while in DNA-RNA base pairs thymine bonds to uracil.
two hydrogen bonds holds adenine and thiamine together and three hydrogen bonds holds guanine and cytocine.

Its complementary base is guanine
guanine
G = guanine, a purine base in DNA. A = adenine, a purine base in DNA C = cytosine, a pyrimidine base in DNA T = thymine, a pyrimidine base in DNA DNA is a double helix and the two strands are held together by hydrogen bonds between A & T (2 bonds) and G & C (3 bonds). The 'rung steps' are either an A & T or a G & C.
The nitrogenous base, Cytosine, pairs with the nitrogenous base, Guanine.In DNA:Cytosine - GuanineAdenine - ThymineIn RNA:Cytosine - GuanineAdenine - Uracil
The bonds of the atom are covalent where as the bonds between the base pairs are hydrogen.
It breaks the hydrogen bonds between the base pairs
