7.2 Transcription and gene expression: Methylation and Epigenetics

Understanding that:

-The environment of a cell of an organism has an impact on the gene expression and thus has the ability to be inherited by the offspring
- One type of marker = methyl group is added to cytosine = methyl cytosine
- Methylation can inhibit transcription and switch off gene expression
- environmental factors can influence the patter of methylation and gene expression
