3. Nucleic Acids

4. Functions of Nucleic Acids Contain genetic material Nucleic acids hold information that our body uses to make proteins

5. Monomers of Nucleic Acids  NUCLEOTIDES are the monomers of nucleic acids

6. Nucleotides are made of…  1 phosphate  1 sugar  1 nitrogen base

7. What is the monomer of nucleic acids? Nucleotides What are the parts of a nucleotide? Phosphate, Sugar, Nitrogenous Base QUICK CHECKS

8. Examples of nucleic acids DNA (double helix) RNA (single strand)

9. What do nucleic acids do for our bodies? Store genetic material, help make proteins QUICK CHECKS

10. Independent Practice  What is the monomer of a lipid?  Why do large groups of lipids form?  Are lipids polymers? Why or why not?  What is the monomer of a nucleic acid?  What are the three parts of the nucleic acid monomer?  What do nucleic acids do for our bodies?
