This is a A level Biology OCR Genetic Engineering Booklet that will last the whole lesson. It covers : The basic process of Genetic Engineering Methods how the gene is obtained Restriction enzymes and their Recognition sites Vectors used to get the genetic material into the desired cell

This OCR A level Biology Resource on Gene therapy is a full lesson of learning the past, present and future of Gene therapy. It covers : The process of gene delivery and their main mechanisms vectors for gene delivery and their advantages/disadvantages Some key Trials that took place in the past their results and set backs It covers the key difference between Somatic cell gene therapy and Germ line gene therapy and what their future challenges are.

A level -Biology -Plant responses Topic -Lesson on Plant responses to Herbivory This includes An introduction to Herbivory what it is and the cost to the producer The types of defences plant use including Mechanical defences -spikes, hairs, barbs etc Moving defences -specifically Mimosa Pudica Chemical defence - Alkaloids with examples Chemical defence - Phenols with examples Chemical defence - Terpenoids with examples Phenological defences - Volatile Organic compounds and Pheromones with examples links to videos on the internet and a summary

This power-point can go with the Booklet or on its own. It covers a whole lesson on the mechanisms that control gene expression in eukaryotes and prokaryotes. These include Transcription control e.g Chromatin remodelling and histone modifcation Post -transcriptional control e.g RNA processing and editing Translational control e.g Inhibitory proteins and initiation factors Post -translational control e.g phosphate groups and protein shortening

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
