  1. Genetic Code II:

    Slide 1 - Genetic Code II:

    • Translation
  2. Review:

    Slide 2 - Review:

    • The Genetic Code explains how DNA contains “coded” information in cells
    • The information stored in DNA is used to create the many proteins that make up living things
    • The DNA is the “recipe” and the protein is the “product”
    • The first step in the process involves copying the information in the DNA into another form: RNA
    • RNA is also a nucleic acid, but has three key differences
    • The process of transcription involves taking DNA and using it to build RNA. This occurs in the nucleus.
  3. Step 2: Decoding the Information =Translation

    Slide 3 - Step 2: Decoding the Information =Translation

    • RNA  PROTEIN
    • Nucleotides  Amino Acids
  4. CODON CHART

    Slide 4 - CODON CHART

    • CODON = 3 letter combination in RNA
    • Codons “code for” specific amino acids
    • Ex: UCG = serine
    • STOP codons = STOP!

  7. Summary of Transcription and Translation

    Slide 7 - Summary of Transcription and Translation

    • Transcription
    • Translation
    • Where does it occur?
    • NUCLEUS
    • RIBOSOME (“protein factory!”)
    • What does it start with?
    • DNA
    • RNA
    • What does it end with?
    • RNA
    • Protein (long chain of amino acids)
