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.

This resource covers the OCR syllabus on PLant transport- Translocation. Firstly it defines what translocation is and then further explains the key terms of source and sink regarding the translocation of sugars. The booklet then further explains the key cells the make up the Phloem tissue, their components and functions. It then goes on to explain the content of the sieve tubes and the reason why Sucrose is transported not glucose. The resource then explains how translocation occurs using the mass flow hypothesis. It shows the key mechanism how Sucrose is loaded into the phloem using a co-transporter. The booklet then shows with clearly labelled diagrams how sucrose is moved along the phloem. The finishing page focuses on the difficult 2021 Translocation question on how glucose produced in photosynthesis is translocated to parts of the plant where glucose is metabolised and stored.

This essential booklet covers the key aspects of organisation of the nervous system which includes: The central nervous system recap of a relay neurone Diagrammatic section of a reflex arc The Peripheral Nervous system Somatic Nervous system Autonomic Nervous system How the nervous system is organised The motor pathways for the autonomic and Somatic nervous systems The sympathetic subsystems The Parasympathetic subsystems Consolidation questions

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 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.
