Presentation Transcript

  1. Rosalind Franklin and Maurice Wilkins

  2. James WATSON and Francis CRICK

  3. D N A • Deoxyribonucleic acid • It’s a polymer • 3 parts: sugar, base, phosphate • Sugar: deoxyribose • Bases: 2 classes-purines (AG) and pyrimidines (CT)

  4. Purines

  5. Pyrimidines

  6. The DNA Song • We love DNA made of nucleotides • Sugar, phosphate and a base • Binded down one side. • Adenine and thymine make a lovely pair • Cytosine without guanine would feel very bare. • (tune of Row, Row, Row Your Boat)

  7. DNA…strands run ANTIPARALLEL

  8. Important because…. • In REPLICATION, DNA polymerase can only add nucleotides to the free 3 ‘ end, NEVER EVER EVER to the 5’ end

  9. Prokaryotic vs. Eukaryotic DNA • Pro—long double helix with its ends joined to form a circle • Eu-arranged in chromosomes • PRO EU
