Gene Regulation
- Complete copy of DNA
- except ganetes
- Sex cells
- Original Code
- cell looks and acts different
- made into proteins
- contain full set of genes
- except gametes
- expressed in specific cells
- genes can be turned on and off in many ways
- wasteful to produce proteins when no lactose to be digested
- when no lactose a repressor protein blocks transcription
- when present it binds to the repressor protein and moves away
- the lac of genes are then translated into digestive proteins
