1. Regulating Gene Expression To accompany “Regulating Gene Expression” Packet -review packet reading, pictures, and questions

2. All of your cells contain the same DNA. So how do you have specialized cells? Genes can be turned on and off within each cell type. Why is gene regulation important??? Diff proteins are produced by diff cell types  diff shapes  diff functions

3. Prokaryotes

8. Eukaryotes- After Translation (simple version) Different “tags” send proteins to different locations w/in the cell “tags” = signal sequences
