Concept explainers
Interpretation:
The sugars in DNA and RNA and the difference between the both has to be given.
Concept Introduction:
Composition of
Sugar: In both DNA and RNA, sugar portion is found. In DNA, the sugar is D-ribose, where at 2’hydroxyl group is absent and in RNA, the hydroxyl group is present at 2’.
Nitrogenous bases: Five types of nitrogenous bases (has unique one-letter code A, G, T, U, and C) are derived from two parent compounds called purine and pyrimidine. The purine derivatives are Adenine and Guanine are two fused nitrogen containing rings. The pyrimidine derivatives are Thymine, Cytosine, and Uracil are nitrogen containing six-membered ring. Adenine, Guanine, Thymine, and Cytosine are the nitrogenous bases present in DNA. Adenine, Guanine, Cytosine and Uracil are the nitrogenous bases present in RNA.
Nucleotide: (Nucleoside + phosphate)
Nucleotides are the building blocks of nuclei acids; monomers of DNA and RNA
Nucleoside and its naming: The combination of monosaccharide (sugar) and nitrogenous base is known as nucleoside.
Numbering the atoms in sugar and base rings:
In order to distinguish the atoms in the sugar of a nucleoside and atoms of a base ring, numbers without prime is used for atoms in the base ring and numbers with prime used for the atoms in the sugar ring.
