Nucleic acids DNA DNA (deoxyribonucleic acid) is the genetic material. An important function of DNA is top store information regarding the sequence of amino acids in each of the body’s proteins. This "list" of amino acid sequences is needed when proteins are synthesized. Before protein can be synthesized, the instructions in DNA must first be copied to another type of nucleic acid called messenger RNA. Structure of DNA Nucleic acids are composed of units called nucleotides, which are linked together to form a larger molecule. Each nucleotide contains a base, a sugar, and a phosphate group. The sugar is deoxyribose (DNA) or ribose (RNA). The bases of DNA are adenine, guanine, cytosine, and

Unformatted text preview: thymine. Notice that the carbon atoms in one of the nucleotides diagrammed below have been numbered. The diagram below shows how nucleotides are joined together to form a "chain" of nucleotides. DNA is composed of two strands in which the bases of one strand are hydrogen-bonded to the bases of the other. The sugar-phosphate groups form the outer part of the molecule while the bases are oriented to the center. The strands are twisted forming a configuration that is often referred to as a double helix . The photograph below is of a model of DNA....
