Can you describe the structure of the DNA MOLECULE?

The Dna molecule is an antiparallel double helix made up of a sugar, a phosphate group and different bases pared with each other. These basis are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T) and are paired up following strict rules. As are always with Ts and Gs are always with Cs. More specifically, As are bonded to Ts by a double hydrogen bond, while Cs are linked to Gs by a triple hydrogen bond. This is what gives the DNA its shape.
