Phosphate group is attached to the 5′-carbon of deoxyribose sugar of one nucleotide and 3′-carbon of the deoxyribose sugar of next nucleotide. Phosphate group provides strong negative charge to the nucleic acid. The bond between phosphate and deoxyribose sugar is phosphodiester bond.Nucleic Acids Nucleotides join together through phosphodiester linkages between the 5' and 3' carbon atoms to form nucleic acids. The 3' -OH of the sugar group forms a bond with one of the negatively charged oxygens of the phosphate group attached to the 5' carbon of another sugar.The pentose sugar in DNA is deoxyribose, and in RNA, the sugar is ribose (Figure). The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and hydrogen on the deoxyribose's second carbon.Nucleic acids are formed when nucleotides come together through phosphodiester linkages between the 5' and 3' carbon atoms. A nucleic acid sequence is the order of nucleotides within a DNA (GACT) or RNA (GACU) molecule that is determined by a series of letters.The diagram shows a nucleic acid in the shape of a double helix. Which sugar is present in the nucleic acid that is represented in the diagram? a:phosphate b:uracil c:deoxyribose d:ribose
Structure of Nucleic Acids: Nucleotides and Nucleic Acids
The diagram shows a nucleic acid in the shape of a double helix. mc008-1.jpg Which sugar is present in the nucleic acid that is represented in the diagram?Nucleotides are chemical compounds that form the basic structure of nucleic acids like RNA and DNA. The chemical structure of nucleotides is almost the same regardless of whether or not the nucleotide is an RNA or DNA nucleotide. Nucleotides are made out of elements like nitrogen and carbon with a nitrogenous base, a five-carbon sugar component, and a group of phosphates.Nucleic acids are the most important macromolecules for the continuity of life.They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals.The diagram shows a nucleic acid in the shape of a helix. mc006-1.jpg Which sugar is present in the nucleic acid that is represented in the diagram?

Basically, nucleic acids can be subdivided into two types: deoxy-ribonucleic acid (DNA) and ribonucleic acid (RNA). Both DNA and RNA have been shown to consist of three groups of molecules: pentose (5-carbon-atom) sugars; organic bases; and inorganic phosphate. Sugars There are only two types of sugar present in nucleic acids, ribose which2. Human genetic material is represented in the diagram 3. The diagram below represents genetic material. below. The region labeled A is made up of a section of A) a protein that becomes an enzyme B) DNA that may direct protein synthesis C) a carbohydrate made from amino acids D) glucose that may be copied to make DNAA DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is a nucleic acid composed of nitrogenous bases (adenine, cytosine, guanine, and thymine), a five-carbon sugar (deoxyribose), and phosphate molecules. The nucleotide bases of DNA represent the stair steps of theDNA stands for Deoxyribose Nucleic Acid while RNA stands for Ribose Nucleic Acid. Compounds of Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorus. Made up of Nucleotide Monomers (Polynucleotides). A nucleotide consists of a Nitrogenous base, a Pentose Sugar & Phosphate Group.Complete hydrolysis of chromosomal nucleic acids gave inorganic phosphate, 2-deoxyribose (a previously unknown sugar) and four different heterocyclic bases (shown in the following diagram). To reflect the unusual sugar component, chromosomal nucleic acids are called deoxyribonucleic acids, abbreviated DNA. Analogous nucleic acids in which the
