  1. DNADeoxyribonucleic Acid Mrs. Ward’s Science Class Ridge RoadMS

  2. Warm-Up Page 35 • Sketch the following diagram of DNA in your science notebook…

  3. Announcments: • Welcome Back! I hope you had a wonderful & restful weekend! • Grades/Third Quarter • Fetal Pigs • Set Up Notebooks • Quiz Thursday on DNA

  4. What is DNA??? • DNA is the common name for DEOXYRIBONUCLEIC ACID • DNA is the genetic material found in all living cells • The majority of DNA is located within the nucleus of EACH and every cell in the body http://www.youtube.com/watch?v=eOvMNOMRRm8&feature=player_embedded#!

  5. What is the structure of DNA? • DNA structure was discovered by James Watson and Francis Crick in 1953 • Described as a “DOUBLE HELIX” • Like a twisted ladder. • The scientists wrote a book by the same name

  6. DNA is: • Made up of: • a sugar-phosphate backbone • (Sides of the DNA) • Four chemical Bases (that match up) • ADENINE, GUANINE, CYTOSINE, and THYMINE • AGCT (RUNGS OF THE LADDER) • A always pairs with T • G always pairs with C • This is how DNA is able to split and replicate and keep the same genetic material. (The cells match up the pairs like a puzzle!)

  7. Another video…about base pairs! • http://www.youtube.com/watch?NR=1&feature=endscreen&v=5raJePXu0OQ

  8. Brain Pop!!!DNA http://www.brainpop.com/science/cellularlifeandgenetics/dna/

  9. An Activity • Find your DNA match!!! • Each of you has a card with a number. • Find your pair and line up. • The class that completes it in the shortest time will get a treat tomorrow.

  10. EXIT TICKET • Where is DNA located? • What is the name of the structure? • APPLY YOUR KNOWLEDGE: • Why might DNA be important in paternity testing?
