1. Proteins & Nucleic Acids

2. Stated Clearly

3. Review: Protein
Organisms are a collection of traits!

4. Review: DNA Every cell of every organism has genetic information
Entire set of DNA for an individual organism

5. Review: Macromolecules
Large organic carbon compounds
Carbohydrates (Photosynthesis & Respiration)
Lipids (Cell Membrane)
Proteins
Nucleic Acids

6. Nucleic Acid Structure
Monomer: Nucleotide
5-Carbon Sugar
Phosphate Group
Nitrogen Base
Polymer: DNA or RNA strands

7. Nucleic Acid Function Biological Functions:
Storage of heritable information
Helps make protein

8. Protein Structure Monomer: Amino Acid Polymer: Protein
Carboxylic Acid (C & O)
Amine Groups (N & H)
Polymer: Protein

9. Protein Function
Biological Functions:
Build & repair tissues

10. Process: Gene Expression
Molecular process of converting DNA genes into a trait

11. Gene Expression Detailed Process

12. Gene Expression Basic Process
Stage 1: Transcription
Gene (section of DNA) is converted into mRNA code
Stage 2: Translation
mRNA, tRNA, rRNA link amino acids based on code
Stage 3: Folding
Polypeptide chain is folded into a specific protein shape
