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 resource booklet explores the Biological importance of water to life and how the key biochemical properties of water enable life to exist on our planet.

This extremely challenging content is easily explained in the OCR Biology A level Sliding Filament Theory Booklet It includes : Skeletal muscle Histology The structure of the myofibril The structure of a sarcomere How the muscle contracts -sliding filament theory How contractions change the pattern of banding Maintenance of ATP

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
