Topic 1.4: DNA and protein synthesis (Edexcel A-level Biology B)

This bundle of 6 fully-resourced lessons have been designed to cover the content as detailed in topic 1.4 of the Edexcel A-level Biology B specification. The specification points in this DNA and protein synthesis topic which are covered by the lessons are as follows:

• The structure of DNA
• The semi-conservative replication of DNA
• A gene is a sequence of bases on DNA that codes for an amino acid sequence
• The structure of mRNA
• The structure of tRNA
• The process of transcription
• The process of translation
• Base deletions, insertions and substitutions as gene mutations
