1. Nucleic Acids

2. Learning Objectives
Describe the relationship between nucleotides and nucleic acids
Name the two types of nucleic acids

3. Two Types of Nucleic Acid
DNA:
(Deoxyribonucleic acid)
Contains the instructions that controls the cell.
RNA:
(Ribonucleic acid)
Uses instructions from DNA to build proteins.

4. Monomer of Nucleic Acids Nucleotide
Nucleic acids are polymers assembled from individual monomers known as nucleotides.

5. Parts of a Nucleotide Phosphate Nitrogenous Base Sugar
One sugar, one phosphate and one nitrogenous base make a nucleotide.

6. Structure of DNA
The DNA backbone is made of alternating phosphates and deoxyribose sugar
The rungs are nitrogenase bases
Nitrogenous Bases
= Deoxyribose Sugar
= Phosphate

7. Function of Nucleic Acids
Large complex molecules that store and transmit hereditary information for all living things

8. Model DNA using marshmallows

9. Sugar – large white 8
Phosphate – sm. white 8
Base – candy corn 8
Toothpicks 12-15
