1. DNA Structure and Function

2. DNA Genetic instructions –Passed on Genes encode proteins –Gene = information –Protein = action hero (does the work)

3. A DNA Helix ATGCATGC Vector DNA color by Greg Emmerich is licensed under CC BY-SA 2.0 Two strands Each made of nucleotides

4. Double Helix Two complementary strands –Complementary base pairing –A with T –C with G

5. Genes encode Proteins Gene sequence –Order of nucleotides in DNA –A, G, C, T –Specific order (spelling) –  specific protein –Amino acid sequence of protein

9. In cells DNA sequence (genotype) –-> transcribed to RNA RNA –-> translated to protein Protein does some job –> contributes to phenotype –Measurable/observable trait

10. Genotype & Phenotype Genotype –Genetic makeup Phenotype –Appearance (or measurable trait)
