2. Why are proteins important??? Almost every function in your body is performed by proteins

3. What are proteins??? Proteins are polymers of amino acids Amino acids chains/proteins can be called polypeptides

4. There are 20 amino acids

5. A U C G A T C G DNA to RNA to protein 4 letters 4 letters 20 letters AMINO ACIDS DNA RNA Protein Singlet, doublet or triplet code?

6. Start codon

7. Nirenberg and Matthaei experiment (1961) Ochoa enzyme: DNA-independent RNA polymerase

8. Transfer RNA

9. Nirenberg and Leder experiment (1964) Identified 54 out of 64 codons

10. Together, Nirenberg and Khorana’s experiments could identify 61 out of 64 codons

11. Open reading frame Start codon stop codon

12. Wobble hypothesis
