Gene expression, epigenetics and the effects of mutations

What this note covers

1. Differentiation depends on selective expression
2. Transcription factors link signals to gene activity
3. Epigenetic modifications change regulation without rewriting base order
4. Environment, expression and phenotype must be linked carefully
5. Sequence mutations have different possible consequences
6. Cell lineage and evidence determine what can be inherited
7. Interpreting a gene-expression comparison without changing the DNA story
8. Tracing a mutation through cell lineage and molecular function
