OCR control of gene expression

This comprehensive resource covers control of gene expression to a high A-level standard for the new OCR 2024 specification. Covering specification points 6.1.1 a, b, c and d across a 53 page PowerPoint with exam style questions and answers. This can be used as several whole lessons, revision, home learning or for note-taking.

Covering:
-types of gene mutation and their effect on protein production (insertion, deletion of one or more nucleotides)
-regulatory mechanisms that control gene expression
-transcriptional: lac operon and transcription factors in eukaryotes

• post-transcriptional: editing of primary mRNA and removal of introns
• Post-translational activation of cyclic AMP
• Genetic control of the development of body plans (homeobox and hox genes)
• Importance of mitosis and apoptosis as mechanisms controlling the development of body form
