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

This Booklet covering the main four structures and levels of proteins from the primary level with Amino acids structure and properties to the Quaternary level with Collagen and Heamoglobin

This introduction to Biological molecules looks at the key chemical groups found in living molecules a long with the basic summary of all the key Biological molecules found in living organisms

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

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.

This Booklet explores the key biological molecule of Carbohydrates exploring monosaccaharides first and then moving on to complex carbohydrates such as starch, cellulose and glycogen

This Biotechnology booklet Introduces some key terms regarding Biotechnology and the many different uses of microorganisms in Biotechnology. The introduction of Primary and secondary metabolites and when they are produced in the microbial growth curve. There are some deep level thinking questions to challenge learners. The booklet then goes on to explain some key Biotechnological processes and the microbes involved covering : The production of food, pharmaceutical drugs, commercial enzymes and Bioremediation. The booklet then introduces industrial scale fermenters and the key factors that can affect microbial growth. The booklet contains picture of a standard fermenter and a power point resource that pupils can use to label and learn the key parts. The Booklet then briefly compares Batch and Continuous culture and the key differences between them. The last page contains the key terms of aseptic technique, asepsis and Contaminants and the results of what happens if contaminants enter in the fermenter and why asepsis is key to pure culture. Lastly the challenges faced when scaling up small scale fermenters to industrial scale.

This A level Booklet resource contains all the vital information needed on the evolution and formation of new species. The booklet is designed to be filled in with the class as you teach them about the two main mechanisms of Allopatric and Sympatric Speciation The booklet introduces Demes and the idea of reproductive isolation and Genetic drift. It then goes into the main types of speciation: Allopatric and Sympatric speciation with some very clear and easy to understand examples. The booklet finishes on other sympatric speciation mechanisms such as Ecological, Temporal and Mechanical isolation.

This full interactive lesson booklet on DNA sequencing defines DNA sequencing then starts off explaining past techniques such as shot gun sequencing step by step and their associated problems. The booklet then focuses on Fredrick Sangers technique of DNA sequencing and how he first cracked the process using radioactive dideoxy nucleotides. The technique goes into detail step by step. The booklet then focuses on modern day sequencing and Next Gen sequencing. The booklet then focuses how flourescent dyes and high processing power computers have dramatically changed the rate at which DNA is sequenced. Lastly the uses of DNA sequencing have been covered
