1 DNA Objective 1

2 Brainstorm DN A CSI Jurassic Park

3 General Description of DNA DNA stands for Deoxyribonucleic Acid DNA is the blueprint for life on our planet DNA has a spiral shape called a double helix –It looks like a ladder that has been twisted Genes are codes in our DNA –DNA ~ Chromosome ~ Genes

4 Review What does DNA stand for? What does DNA look like (use the scientific name for its shape)?

5 DNA Intro: Jurassic Park FACTFICTION

6 DNA Structure DNA is a Nucleic Acid (polymer) The monomers for DNA are nucleotides –Adenine - A –Guanine - G –Cytosine - C –Thymine - T

7 DNA Structure Sides of the ladder are made of sugars and phosphates (backbone/support) The rungs of the ladder are nitrogen bases (represented by the letters A, G, C, T) A  T –(Always Together) C  G

8 Review What type of molecule is DNA? What supports the shape of DNA? What bases go together?

9 DNA Intro: DNA In Our Lives 1.What is proposition 69? 2.What is required now that it’s 2009? 3.Where can DNA samples be taken from? 4.Do you agree with proposition 69? 5.Do you think everyone should have their DNA registered?
