This lesson describes how recombinant DNA can be produced, including the role of restriction endonucleases and DNA ligase. The PowerPoint and accompanying resources have been designed to cover the content of point 7.4 (i) of the Edexcel A-level Biology B specification.
This lesson begins with the introduction of recombinant DNA technology as a process where fragments of DNA are transferred from one species to another. Over the course of the lesson, the students are guided through 5 steps in the production of the recombinant DNA, with a focus on the enzymes involved, which are reverse transcriptase, DNA polymerase, restriction endonuclease, and DNA ligase. Understanding checks and prior knowledge checks are used throughout the lesson and the answers are embedded into the PowerPoint to allow the students to assess their progress.
