Biology A Level OCR -Genetics of living systems -Control of gene expression

Having learned about this in my Biochemistry degree. It has now been included in the OCR A level Biology A H420 Syllabus as a kind of introduction into cellular control.
Having taught this for several years I have had to make my own resource as there is very little material out on it that is relevant to A level students and the textbooks don’t explain the Biochemistry fully.
The resource is a Booklet gap fill with diagrams and the teacher telling them all about the various different mechanisms that control gene expression in organisms.
It covers
-Gene regulation-Transcriptional control : chromatin remodelling/Histone modification / Lac operon/cAMP-Post-Transcriptional control: RNA Processing /RNA editing-Translational control : protein kinases/inhibitory proteins/inititaion factors-Post-Translational control : phosphates/amino acid modification/folding proteins/cAMP modification
