When the nitrogenous bases
bind in the center of the helix, adenine tends to bind with thymine, whereas guanine tends to bind with cytosine.
Made up of three components: 1-phosphoric acid, 2-five carbon sugars (ribose or deoxyribose), and 3-a nitrogenous base
, typically a derivative of either purine or pyridimine.
The reader is probably aware that there are four such subparts, and that each of the four consists of a heterocyclic nitrogen-containing molecule (the nitrogenous base
, or just "base," in context); the base covalently linked to a 5 carbon sugar (2'--deoxyribose), with the base plus sugar being referred to as a "nucleoside"; and the nucleoside with the covalent addition of one, two, or three phosphate groups to the 5' carbon, which respectively make up a nucleoside mono-, di-, or triphosphate (collectively referred to as a "nucleotide").
To investigate the ability of 2HT and IMZ-O to form nitrogenous bases
via thermal degradation during vulcanization, their thermal stability was investigated by means of thermogravimetric analysis.
Instead of using the four nitrogenous bases
of DNA, in this study the researchers used three monomers .
