  2. Nucleotide - Wikipedia

    en.wikipedia.org/wiki/Nucleotide

    This nucleotide contains the five-carbon sugar deoxyribose (at center), a nucleobase called adenine (upper right), and one phosphate group (left). The deoxyribose sugar joined only to the nitrogenous base forms a Deoxyribonucleoside called deoxyadenosine, whereas the whole structure along with the phosphate group is a nucleotide, a constituent of DNA with the name deoxyadenosine monophosphate.

  3. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    Secondary structure is the set of interactions between bases, i.e., which parts of strands are bound to each other. In DNA double helix, the two strands of DNA are held together by hydrogen bonds. The nucleotides on one strand base pairs with the nucleotide on the other strand. The secondary structure is responsible for the shape that the ...

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    The nucleotide contains both a segment of the backbone of the molecule (which holds the chain together) and a nucleobase (which interacts with the other DNA strand in the helix). A nucleobase linked to a sugar is called a nucleoside, and a base linked to a sugar and to one or more phosphate groups is called a nucleotide.

  5. Nucleic acid - Wikipedia

    They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). If the sugar is ribose, the polymer is RNA; if the sugar is deoxyribose, a variant of ribose, the polymer is DNA.

  6. Deoxyribonucleotide - Wikipedia

    en.wikipedia.org/wiki/Deoxyribonucleotide

    A deoxyribonucleotide is a nucleotide that contains deoxyribose.They are the monomeric units of the informational biopolymer, deoxyribonucleic acid ().Each deoxyribonucleotide comprises three parts: a deoxyribose sugar (monosaccharide), a nitrogenous base, and one phosphoryl group. [1]

  7. Ribonucleotide - Wikipedia

    en.wikipedia.org/wiki/Ribonucleotide

    Eventually, Levene was able to identify the correct order of which the components of RNA and DNA are put together, a phosphate-sugar-base unit, in which he later called a nucleotide. Although the order of nucleotide components were well understood by Levene, the structure of nucleotide arrangement in space and its genetic code still remained a ...

  8. Biomolecular structure - Wikipedia

    en.wikipedia.org/wiki/Biomolecular_structure

    Biomolecular structure is the intricate folded, three-dimensional shape that is formed by a molecule of protein, DNA, or RNA, and that is important to its function.The structure of these molecules may be considered at any of several length scales ranging from the level of individual atoms to the relationships among entire protein subunits.

    More detailed comparisons with such ab initio quantum computations are in principle obtainable through 2D-FT NMR spectroscopy and relaxation studies of polynucleotide solutions or specifically labeled DNA, as for example with deuterium labels. In an interesting twist of roles, the DNA molecule was proposed to be used for quantum computing via DNA.
