1. Genes

2. Genes
Cells come in all different varieties, each with a different function
Genes are found in the nucleus and the mitochondria of your cells
In all you have about 20,000 genes

3. Genes are small sections on DNA molecules
When lined up, the DNA in one cell is several feet long
In order for it to fit inside the nucleus it is coiled up

4. Genetic Code
The order of your nitrogen bases spell out the language for the genetic code
This code determines what you are (species) – each species has their own order of bases
Genes are the recipe (instructions) for making specific proteins

5. The proteins your cells make determine your specific traits
Your traits are things like hair color, height, blood type

6. Genes tell a cell how to function and what traits to express (show)
Gene regulators turn different genes on or off in different cells to control cell function

8. What are genes?
Explain how your genes determine your traits.
