Every nitrogenous base shares one feature: a six-sided ring with 4 carbon atoms and 2 nitrogen atoms. This article will, however address a different aspect of the virus. ADDING IN THE BASES • The bases are attached to the 1st Carbon • Their order is important It determines the genetic information of the molecule P P P P P P G C C A T T 16. . While they are similar in many respects, there are a number of key differences between them that you will be expected to know for the AP® exam. The four nitrogenous bases in the DNA are Guanine, Thymine, Adenine and Cytosine. A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. Thymine 4. Nitrogenous Bases 2. 1. RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. The pyridones are aromatic compounds because of … In B-DNA, there are 10 base pairs per turn of the helix, each turn sweeping out 3.4 nm (34 A) of linear translation (see Fig. WATSON-CRICK MODEL Bases form specific base pairs , held together by hydrogen bonds Structure compatible with any sequence of bases 19. Critically, these bases are linked to each other with hydrogen bonds, forming the "rungs" of a structure that, if not wound into a helix, would resemble a ladder; in this model, the sugars and phosphates form the sides. ; Acids only show their properties when dissolved in water. The nitrogenous base is either a purine or a pyrimidine. This is because water can break apart the acid into hydrogen ions and a salt.
