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. WebThe purine's primary structure is two carbon-nitrogen rings.

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. 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 ... ims and sumh bhubaneswarWebDec 30, 2024 · 7.1: DNA Structure. As you can see in Figure1, the nucleotides only vary slightly, and only in the nitrogenous base. In the case of DNA, those bases are adenine, guanine, cytosine, and thymine. Note the similarity of the shapes of adenine and guanine, and also the similarity between cytosine and thymine. A and G are classified as purines, … lithium quilted hooded jacket

"Cytosine (symbol C or Cyt) is one of the four nucleobases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of cytosine is cytidine. In Watson-Crick base pairing, it forms three hydrogen bonds " - Cytosine backbone
