This full 10 page Booklet on
plant hormones
plant responses to herbivory
seed germination
Apical dominance
Abiotic responses to stress
Tropisms
Tropisms historical investigations
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
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 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
