What you will learn in Same genome, different cells

1. 1. Same genome, different cells

   One gene list across four cell types, with only the levels differing.

2. 2. The lac operon

   Four sugar combinations, and the one a switch model gets wrong.

3. 3. Generalising the logic

   Inducible and repressible operons as one idea pointed two ways.

4. 4. Chromatin, the first gate

   Why a transcription factor cannot help if the DNA is packed.

5. 5. Differentiation as a stable state

   Two identical genomes reaching different fates, and staying there.
