The Structure and Function of Macromolecules Part II: Proteins & Nucleic Acids The FOUR Classes of Large Biomolecules All living things are made up of four classes of large biological molecules: The printed out notes are more detailed than these slides, you are expected to read the chapter and your notes - anything is fair game on the test, but the cell chapter is largely review. . Quick: Grab some scratch paper and quickly discuss with your partner what you remember from freshman biology about the cell. . Where is the genetic material in a prokaryotic cell?. In a bacterial DNA loop and there may be one or more plasmid rings.. 2. Where is the genetic material in a eukaryotic cell?. The DNA is in chromosomes enclosed in a nucleus. . Vinay. K. .
