  1. What IS This??

  2. Question of the Day Question: How would you describe DNA to a kid? Answer: … … … 2’s Turn In: - Journey into DNA Review

  3. Notes: DNA & RNA

  4. DNA • Located in nucleus • Too large to leave nucleus • Made of nucleotides • Nucleotide has 3 parts: • Deoxyribose sugar • Phosphate • Base: A, T, C, G • Bases always bond in pairs • A & T • C & G

  5. DNA • Watson & Crick discovered structure of DNA • DNA shape= double helix • Received Nobel Prize • Used pictures from Rosalind Franklin Rosalind Franklin James Watson Francis Crick Franklin’s Picture of DNA

  6. DNA

  7. DNA Replication • DNA copied before mitosis and meiosis • New DNA is identical • Occurs during interphase Growth DNA Replication Growth

  8. DNA Replication • Replication: 1. DNA unwinds & unzips 2. Nucleotides are attached with DNA polymerase and ligase • New molecules are attached until anaphase

  9. DNA Replication

  10. RNA • Single stranded • Can leave nucleus • Made of nucleotides • Nucleotide has 3 parts: • Ribosesugar • Phosphate • Base: A, U, C, G • Bases always bond in pairs • A & U • C & G

  11. RNA • Used carry information outside of nucleus • Like a photocopy of DNA

  12. Lab: Berry Full of DNA

  13. Berry Full of DNA • Put your strawberry in baggie • Mush 2 minutes • Add 10 mL of extraction buffer • Mush 1 minute • Filter with cheesecloth & funnel • Add ethanol

  14. Personal DNA

  15. Would you want your DNA analyzed? Why or why not? Explain in detail using examples. Exit Ticket:
