WebAlso, a pyrimidine is always H bonded to a purine so that the diameter/width of the DNA molecule is consistent throughout the molecule. 2 purines would make the DNA bulky in parts and 2 pyrimidines would make it very narrow. By always pairing a 1 ring base with a 2 ring base the width is constant. WebMar 1, 2024 · Nucleotides are made up of 3 parts. The first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine. In RNA, thymine is replaced by uracil. These nitrogenous bases are either purines or pyrimidines. Base pairs are formed when adenine forms a hydrogen bond with thymine, or cytosine forms a hydrogen bond with guanine. landscape london skyline
