  1. DNA and RNA The Code of Life The Human Genome Project

  2. Engage:Instruction For A Human Being

  3. Remember: Strawberry DNA Lab What did your Strawberry DNA look like?

  4. Explore DNA Experiment for Parents!!! • Tonight, I want you to attempt to extract DNA from different types of food in your home. • You are to discuss and explain this process to your parents.

  5. Review/Explain:Types of Nucleic Acids What are the two types of nuclei acids? Ribonucleic Acid (RNA) – Single Stranded Deoxyribonucleic Acid (DNA) • Double Helix • (Twisted Ladder)

  6. DNA • Deoxyribose Sugar • Base Pairs A-T G-C • Phosphate • Most Importantly--- • Contains the Code for ALL the Proteins in the Body

  7. RNA • Ribonucleic Acid (RNA) • Sugar + Phosphate Backbone • Differs from DNA • Single Stranded • Ribose Sugar • Base Pairs A-U, G-C • Are there T’s in RNA? • A, U no T’s in RNA • RNA assists DNA in manufacturing needed proteins

  8. Questions • Name one difference between DNA and RNA. • DNA – Double Helix, RNA – Single Stranded • DNA --- A-T, RNA ---A-U • DNA ---Deoxyribose Sugar, RNA---Ribose • What is a similarity of DNA and RNA? • G binds with C in both DNA and RNA • Both have sugar and phosphate backbone

  9. Getting The Letters Out

  10. Practice • On your paper, complete the missing DNA strand by adding the complementary bases. • A T C G T T G C C A T C • T A G C A A C G G T A G • Make the complementary RNA strand for the single strand of DNA below: • A A T C A T C A C G T T • U U A G U A G U G C A A

  11. Get Your DNA Jewelry

  12. Elaborate:Make a Key for your DNA Model • Label each of the following components: • Cytosine • Adenine • Guanine • Thymine • Phosphate • Deoxyribose

  13. DNA to RNA • Using your DNA model and notes, what changes would you have to make in order to change this into an RNA molecule?

  14. DNA • What is the Main Job of DNA? • It contains the code for the proteins an organism may produce. • What are the basic units or monomers of DNA? • Nucleotides make up DNA. • Where is DNA found? • It is found mostly in the nucleus of a cell making up its chromosomes.

  15. RNA • What is the Main Job of RNA? • It retrieves the protein code from DNA and carry out the processes needed to produce proteins. • What are the basic units or monomers of DNA? • Nucleotides • Where is RNA found? • It is found both inside and outside of the nucleus.
