Cytosine backbone
WebAdenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring. Cytosine and thymine are pyrimidines which are structures composed of a single six-sided ring. Adenine always binds to … WebNow let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base ( Figure 9.3 ). There are four types of nitrogenous bases in DNA.

WebMar 1, 2024 · Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are classified as purines. The primary structure of a purine is two carbon-nitrogen rings. Cytosine, thymine, and uracil are classified as pyrimidines which have a single carbon-nitrogen ring … 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. Additionally, the GC and AT base pairs have ...
WebDeoxyribose is one of the three components of nucleotides, the building blocks of DNA. Each nucleotide consists of a phosphate group, a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G)—and deoxyribose. DNA's sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring.
