Sugar and phosphate molecules.
Ribonucleotide is made up of a deoxyribose sugar, a nitrogenous base and one or more phosphate groups. This sugar has a chemical formula of C5H10O3. On the other hand Ribonucleotide molecule also has nitrogenous base and a phosphate group that are attached to a ribose sugar rather than a deoxyribose sugar. The chemical composition of ribose sugar is C5H10O5. Thus there are 3 oxygen atoms in DNA, whereas there are 5 oxygen atoms in RNA. PHOSPHATES AND SUGAR The two sides of DNA latter are made up of molecules of a sugar called deoxyribose alternating with molecules known as phosphates. Edit. Share to: Karlene Edinger. The backbone of DNA is formed by sugar (deoxyribose) and phosphate. 5 people found this useful. Edit.

A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar, … and a nitrogenous base. These nucleotides connect together to form the double-stranded structure, called the double helix. The backbone of DNA is formed by sugar (deoxyribose) and phosphate. 5 people found this useful.

DNA is a long string of these blocks or letters. Each nucleotide consists of a sugar (deoxyribose) bound on one side to a phosphate group and bound on the other side to a nitrogenous base. There are two classes of nitrogen bases called purines (double-ringed structures) and pyrimidines (single-ringed structures). The four bases in DNA's alphabet are:  Exploring a DNA chain The sugars in the backbone The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. The full name of DNA, deoxyribonucleic acid, gives you the name of the sugar present-deoxyribose. Deoxyribose is a modified form of another sugar called ribose. The phosphate group on one nucleotide links to the 3' carbon atom on the sugar of another one. In the process, a molecule of water is lost-another condensation reaction. . . . and you can continue to add more nucleotides in the same way to build up the DNA chain. DNA is often said to have a sugar and phosphate backbone.. Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in base pairs, or bpthat is, the number of rungs in the ladder. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes. DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA. DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes. This base-to-base bonding is not random; rather, each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this pattern of bonding looks much like a ladder with sugar-phosphate side supports and base-pair rungs. Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5' side of the sugar (indicated by light gray). Opposite to the 5' side of the sugar molecule is the 3' side (dark gray), which has a free hydroxyl group attached (not shown). Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue) A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next. Genes are made of DNA, and so is the genome itself.
