The nitrogenous bases found in nucleotides are classified as pyrimidines or purines. Purines contain two rings in their structure. Nucleotide really just means a component of a nucleic acid in which you have 3 components: Ribose sugar, Nitrogenous base, and Phosphate (if you are missing the phosphate, these are called nucleosides. Purines are heterocyclic amines consisting of a pyrimidine ring fused to a five-member ring with two nitrogen atoms. With minor modification (substitution of U for T) these rules also apply to dsRNA.Most DNA occurs in nature as a right-handed double-helical molecule known as Watson-Crick DNA or B-DNA (Figure I-1-8). Each strand has a distinct 5′ end and 3′ end, and thus has polarity. Uridine nucleotides: UDP 5. The purines are adenine and guanine. Adenine binds with thymine (A-T) in DNA and with uracil in RNA (A-U). Eric Lam, in Plant Biochemistry, 1997. This can be either DNA or RNA, and it can contain 1/2/3 phosphate groups (mono/di/tri). Double-helical DNA can be denatured by conditions that disrupt hydrogen bonding and base stacking, resulting in the “melting” of the double helix into two single strands that separate from each other. The major purine components of nucleic acids are adenine and guanine residues; the major pyrimidine residues are those of cytosine, uracil (which occurs mainly in RNA), and thymine (5-methyluracil, which occurs mainly in DNA).
