1. DNA Unit Target: Explain why individuals of the same species vary in how they look, function and behave.

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. RNA

5. nitrogen base sugar phosphate group base pair nucleotide hydrogen bonds

6. CharacteristicDNARNA Deoxyribonucleic acid Ribonucleic acid Ribose present Deoxyribose present Adenine present Thymine present Uracil present Guanine present Cytosine present Phosphate group present Formed from nucleotides Double stranded Single stranded Remains in the nucleus Moves out of the nucleus Contains a chemical message or code DNA and RNA Comparison Fill in the tables below using check marks to indicate to which molecule(s) the following characteristics apply.

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

8. Truth or baloney? DNA replication occurs in the nucleus. True DNA replication occurs during mitosis. Baloney- 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

9. Learning Target: Use a diagram to model the roles of molecules and cell structures in protein synthesis. (skill) Nucleus mRNA Ribosome tRNA anticodon Codon mRNA ABCDEFGABCDEFG What is asparagine? An amino acid

10. 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

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

12. Learning Target: Explain Biology’s Central Dogma. (knowledge) Biology’s central dogma refers to the flow of information from DNA RNA Protein
