Purines always bond with Pyrimidines.
Purines pair with pyrimidines.
Each of the base pairs is formed with a purine and a pyrimidine. Even though the size of a purine differs from the size of a pyrimidine, the sum of these sizes is the same. In other words, the size of a guanine base is roughly the same size as an adenine base, and a cytosine is roughly the same size as a thymine. Pairing of G to C and A to T therefore gives a uniform diameter.

DNA, and the shape is also known as a double helix.
DNA molecule is shaped like a spiral staircase and is composed of two parallel strands of linked subunits.
The whole DNA strand is a double helix.
Both DNA and RNA can exist in the double helix form, but only DNA is completely stable as a double helix. The double helix RNA is usually only short "hairpin" sections folding back on itself, never the long essentially linear form of double helix DNA.
DNA is a double helix, or a twisted ladder.
The name of the shape of DNA is called double helix. There are two long strands of DNA connected in several points. These strands twist and look like a spiral or a spring.
DNA is organized in a double-helix fashion.
