12-5: Gene Regulation
- Gene Regulation: An Example
- operon: group of genes that operate together
- lac genes are turned off by
repressors and turned on by the
presence of lactose
- operator: area where repressor binds, "the other region"
- Eukaryotic Gene Regulation
- Most eukaryotic genes are controlled indivuatlly,
regulatory sequences are much more complex than
"lac" operon
- differentiation: cells become more specialized in structure
- hox genes: genes that control differentation of cells and tissues in the embryo
