• 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.

Review/ExplainTypes 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 Ts in RNA?
• A, U no Ts 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

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

ElaborateMake a Key for your DNA Model

• Label each of the following components
• Cytosine
• Adenine
• Guanine
• Thymine
• Phosphate
• Deoxyribose

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.
