For Nucleic acids. . Distinguish between: a. ribose and deoxyribose b. nucleotide and nucleoside c. pyrimidine and purine Remember that nucleic acids are polymers of nucleotides. Compare and contrast the structures/functions of DNA and RNA Explain what keeps the two strands of DNA together Describe the 5’ to 3’ polarity of a nucleic acid polymer Chapter 5 continued – The structure and function of macromolecules (aka biomolecules) As before… Learning objectives: List the four major classes of macromolecules Be able to describe each type of macromolecule in terms of: Elemental composition, molecular structure/subunits, and function(s) Distinguish between monomers and polymers Be able to recognize and illustrate condensation rx and hydrolysis rx

Nucleic Acids Composed of elements: C, H, O, N, & P Monomer subunits: Nucleotides Polymers - Two major kinds: Deoxyribonucleic acid ( DNA ) Ribonucleic acid ( RNA ) Functions * : Storage of genetic information Protein synthesis * [Additional roles of related nucleosides/nucleotides include energy transfers (ATP/ADP), signal transduction (cAMP), & metabolic co-enzymes (NAD/FAD)]
