Biological Molecules - 21 Nucleotides and Nucleic Acids Nucleic acids are our information carrying compounds -- our genetic molecules. As with many of our other compounds, the nucleic acids are composed of subunits of nucleotides. Nucleotides, in addition have independent functions. Functions of Nucleotides Components of nucleic acids (which are long chains of nucleotides) Energy carrier molecules (ATP) Energy transport coenzymes (NAD + , NADP + , FAD + ) Chemical intracellular messengers (e.g., Cyclic AMP, a cyclic nucleotide that carries messages from the cell membrane to molecules within the cell, to stimulate essential reactions)

Unformatted text preview: Functions of Nucleic Acids Storage of genetic information (DNA) Transmit genetic information from generation to generation (DNA) Transmit genetic information for cell use (RNA) DNA self-replication Most of the information on nucleotides and nucleic acids will be discussed when we discuss genetics and energy relationships of cells. For now we shall just present the basic structure of the nucleotides and nucleic acids. Nucleotide Structure 1. 5–carbon sugar component Ribose Deoxyribose 2. Phosphate group Attached to the sugar's 5' carbon with a phosphodiester bond...
