The chemistry of the nitrogenous bases is really the key to the function of DNA. See? copyright 2003-2023 Study.com. Meaning the A=U pairing is very similar to the A=T pairing. o Nucleotides of DNA contain deoxyribose sugar ; Nucleotides of RNA contain ribose o DNA = Thymine ; RNA = Uracil o DNA is double strand helix with complementary base pairing ; RNA is a . 2010-02-06 01:05:36. answer choices. . In DNA, the most common modified base is 5-methylcytosine (m5C). These chain-joins of phosphates with sugars (ribose or deoxyribose) create the "backbone" strands for a single- or double helix biomolecule. Notice that the specific positioning required for hydrogen bonding is only made possible by the inverted nature of one of the two strands. Adenine is a purine base because it has two rings in its structural formula. Guanine and cytosine content (GC or G+C-content) is the percentage of guanine (G) and cytosine (C) in a DNA or RNA molecule out of 4 total bases (guanine (G), cytosine (C), adenine (A), thymine (T). I would definitely recommend Study.com to my colleagues. Bases pair off together in a double helix structure, these pairs being A and T, and C and G. RNA doesn't contain thymine bases, replacing them with uracil bases (U), which pair to adenine 1. These extra oxygen atoms allow Guanine to form an extra hydrogen bond, accounting for its extra stability when compared to Adenine. It is mainly concerned with the interrelationships between DNA, RNA and protein synthesis.
