Sugar On A Dna Diagram. The two chains are held together by hydrogen bonds. The sugar found in rna is ribose whereas the sugar found in dna is deoxyribose both of which are 5 carbon sugars.
A nucleotide has three components. The sugar in dnas nucleotides is called deoxyribosedna is an abbreviation for deoxyribonucleic acid. The building blocks of dna are nucleotides which are made up of three parts.
This structure is described as a double helix as illustrated in the figure above.
These bonds are covalent bonds known as phosphodiester bonds. The two chains are held together by hydrogen bonds. The phosphodiester bonds link the 5 carbon of one deoxyribose sugar molecule to the phosphate group from the same nucleotide which is itself linked by. A five carbon sugar called deoxyribose labeled s.
