Adenine

Detailed explanation-1: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds. That is also the reason why the two strands of a DNA molecule can be separated more easily at sections that are densely populated by A-T base pairs.
Detailed explanation-2: -In DNA, adenine binds to thymine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. Adenine is one of the two purines nucleobases utilized in the process of forming nucleotides of the nucleic acids. Adenine also bonds with Thymine in the DNA structure.
Detailed explanation-3: -Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds.
Detailed explanation-4: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
