A Level Biology OCR -Control of gene expression

(1)
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 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

This full lesson Booklet is the perfect resource to inform and educate students in the most latest developments of Biology in the 21st century. The Booklet begins introducing what the advancements in DNA sequencing have done and how they have produced a large amount of processed data and information and that this has resulted in the development of a brand new are n Biology called Bioinformatics. The booklet then explains as a result of all the information gathered comparison studies have been used to look at the firstly the genome size of different organisms and the number of functional genes they possess. The booklet then demonstrates an inter species comparison study looking at Beta haemoglobin and how a single mutation can lead to disease such as sickle cell anaemia and how Bioinformatics can compare all the different species data and find similarities are closely related to each other. The resource then touches on more complex disease such as cancer and the BRCA gene. The Booklet then explains how pharmaceutical companies are using Bioinformatics to focus on SNPs and using them to make new drugs. This then follows on into the NHS current project the 100,000 genome project and how Bioinformatics will be used. The booklet finishes on two exciting future developments using Bioinformatics synthetic Biology and Proteomics.

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 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.

A Level Biology OCR Animal transport - Transport of oxygen, oxygen dissociation curves

(0)
The booklet covers the difficult concept of how haemoglobin transports oxygen around the body and how the haemoglobin undergoes configurational change so that it bonds oxygen more easily after the first oxygen has joined. The booklet then introduces Oxygen dissociation curves why they are sigmoid shape and how they are made including what the partial pressures means in terms of tissues in the body. There are various amount of tasks in the booklet students are challenged to make a dissociation curve with some data and need to answer some key questions on what is happening at different parts of the graph in relation to partial pressure and haemoglobin shape. The booklet then compares haemoglobin with both myglobin the oxygen storage molecule found in muscles and foetal haemoglobin. Both have questions on what these molecules do and where they are situated on the oxygen dissociation curve graph in relation to adult haemoglobin. The booklet then introduces carbon dioxide transport in great detail and the three main methods it is transported in the blood. The booklet then finishes on the Bohr effect and how carbon dioxide affects the oxygen dissociation curve and what happens when different carbon dioxide concentrations affect haemogobin loading and unloading.
