PYF12 32105 804 PM Page 191 repressor activation of the operon by cAMPCAP and control of the operon byposttranscriptional and posttranslational regulatory mechanisms and will be usedto dem. Understanding:. Gene expression is regulated by proteins that bind to specific base sequences in DNA . The environment of a cell and of an organism has an impact on gene expression. Nucleosomes help to regulate transcription in eukaryotes. Chapters 16 and 17. Before the end of the semester we will be covering…. Historical DNA experiments. Structure of DNA/RNA. DNA Replication.
