2.6 Structure of DNA and RNA. Nucleic Acid Structure. Draw the basic structure of a nucleotide, labelling its parts. Differentiate between the different types of nitrogenous bases.
Ribose and Deoxyribose. Sugars that contain five carbon molecules are described as pentose sugars; Ribose and deoxyribose are important pentose sugars found in the nucleotides that make up RNA and DNA; Ribose and deoxyribose are very similar in terms of structure. Deoxyribose has lost one oxygen atom at carbon number 2
Deoxyribose and ribose are both five-carbon sugars that play crucial roles in the structure and function of nucleic acids. However, they differ in one key aspect: deoxyribose lacks an oxygen atom on its second carbon, while ribose has an oxygen atom attached to each carbon.
23 sie 2021 · There are two sugars found in nucleotides - deoxyribose and ribose (Figure 2.128). By convention, the carbons on these sugars are labeled 1’ to 5’. (This is to distinguish the carbons on the sugars from those on the bases, which have their carbons simply labeled as 1, 2, 3, etc.) Deoxyribose differs from ribose at the 2’ position, with ...
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine: Figure 1.2.1: Purines. The most commonly occurring pyrimidines in DNA are cytosine and thymine: Figure 1.2.2: Pyramidines.
DNA is a polymer of nucleotide monomers, each consisting of a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). The nucleotides of DNA are arranged into a double helix based on the rules of base complementarity.
In 1953, James Watson and Francis Crick established the structure of DNA. The structure is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. Color all the phosphates pink (one is labeled with a "p").
