Presentation Transcript

  1. DNA Unit Target: Construct an explanation for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through a system of specialized cells.

  2. Learning Target: Compare and contrast the structures and function of DNA and RNA. (K) DNA or RNA? Made of: Phosphate group Deoxyribose Nitrogen bases DNA DNA or RNA? Made of: Phosphate group Ribose Nitrogen bases RNA

  3. DNA or RNA? Nitrogen bases include: C G A T DNA DNA or RNA? Shape is a double helix DNA

  4. DNA or RNA? Undergoes replication. DNA DNA or RNA? Is transcribed. DNA

  5. Learning Target: Explain and model how the information contained in DNA is copied. (R) DNA is unzipped by an enzyme called • DNA polymerase • Helicase • RNA polymerase B.

  6. Truth or False? DNA replication occurs in the nucleus. True DNA replication occurs during mitosis. False- during interphase DNA replication allows daughter cells to obtain the same genetic information. True DNA replication is semi-conservative. True- one old and one new strand

  7. Learning Target: Use a diagram to model the roles of molecules and cell structures in protein synthesis. (skill) A B C D E F G Nucleus mRNA Ribosome tRNA anticodon Codon mRNA What is asparagine? An amino acid

  8. Learning Target: Use the genetic code to construct a protein’s amino acid sequence. (skill) DNA CGA TTC mRNA? GCU AAG Polypeptide chain? Alanine-lysine

  9. Learning Target: Explain Biology’s Central Dogma. (knowledge) True or False? Biology’s central dogma refers to the flow of information through a cell. True
