Power point slides I currently use to deliver fully the unit “DNA AND PROTEIN SYNTHESIS” for AS Biology. The slides follow Cambridge syllabus (9700) but they are easily adaptable to others.
The topic is divided in:

Intro: starter activity
Structure of DNA and RNA
DNA replication
Genetic code - Features
Protein synthesis: the process
Gene mutations
4 past paper multiple choice questions and some questions/tasks in the different sections.
Power point student version (with blanks) added as token
