Presentation Transcript

  1. Warm Up:Take out homework.What is the shape of DNA?Where is DNA found in cells?What is the monomer (building block) of nucleic acids (macromolecule)? • Homework:Complete DNA completion worksheet (only side 1) http://ed.ted.com/lessons/dna-the-book-of-you-joe-hanson

  2. Nucleic Acids These macromolecules carry the secret of the gene.

  3. DNA Deoxyribonucleic Acid

  4. Nucleotides are the monomers that make up Nucleic Acids. The 5-carbon sugar may be different in other nucleic acids. The sugar in DNA is deoxyribose.

  5. DNA NUCLEOTIDE 3 PARTS: • Sugar Molecule – deoxyribose • Phosphate Group – phosphorous(P) and oxygen (O) • Nitrogen Base – adenine(A), cytosine(C), guanine(G), and thymine(T)

  6. The Nitrogenous bases make each DNA nucleotide different

  7. Circle 1 nucleotide...

  8. DNA strands are complementary to each other. • One strand can be a “template” to find the code of the other, but they are NOT identical • Which bases are complements? • Chargaff’s Rules of Base Pairing

  9. “Sugar-phosphate backbone”The phosphate of one nucleotide is bonded to the sugar of the next.HYDROGEN BONDS!!!

  10. Draw the complementary strand of the following DNA template.

  11. A Twisted Ladder The Double Helix: • Complementary strands are held together by hydrogen bonds

  12. Write answers on whiteboards: • Draw and label the monomer of a Nucleic Acid. • What makes each nucleotide different? Name the 4 nucleotides. • Identify the complementary base pairs • What is the “bond” that holds the complementary DNA strands together? • What molecules make up the “backbone” of DNA?

  13. Brain Pop!!

  14. Build a model of DNA • Make 9 base pairs!!! • Blue tubes = cytosine • Yellow tubes = guanine • Green tubes = thymine • Orange tubes = adenine • White tubes = phosphates • White rods = hydrogen bonds • Purple or black pentagons = deoxyribose (sugar)
