3. How is DNA organized? nucleus genome chromosome DNA gene
Gauge the audience- Has anyone ever seen a diagram like this? Can you name any structures?
Nucleus holds all the genetic info
All of your genetic info is your "genome"
Broken down into chromosomes
A single instruction is called a gene,
All of this material is composed of DNA
gene

4. What does DNA do? Your DNA determines your PHENOTYPE
Instruction book for your cells My
DNA
hair
shape
body
skin
eyes
Each instruction is called a GENE
Genes are the recipes for Proteins
All your genes together is called your GENOME
How your cells read your Genome depends in part on your (and your cells’) environment

5. What does DNA do? Each instruction is called a GENE
Genes are the recipes for Proteins
All your genes together is called your GENOME
Let's go over an example on how cells do this...

8. } DNA found in nucleus (Eukaryotic)
Where is DNA?
DNA is found in the cells of every living organism
There are different types of cells
Animal cells
Plant cells
Bacteria cells
} DNA found in nucleus (Eukaryotic)
- DNA floating loose (Prokaryotic)
What are the 3 types of cells?
If students are stuck, ask “What types of cells makes dogs, zebras, and humans? What types of cells makes roses, broccoli or elm trees? What types of cells are found in yogurt, your gut and sometimes can make you sick?”
Ask students if they know any of the structures of animal cells or plant cells- if not, review: cell membrane, cell wall, nucleus, and DNA, but mention there are many more structures
