This lesson focuses on the structure of RNA and specifically the similarities and differences between this nucleic acid and DNA. The engaging and detailed PowerPoint and accompanying resource have been designed to cover part 1 of point 4.2 of the AQA A-level Biology specification which states that students should be able to describe the structure of molecules of messenger RNA and transfer RNA as well as understand the concept of a genome and proteome. Students were introduced to the detailed structure of DNA in previous lessons covering specification point 4.1, so this lesson is written to tie in with those and continuously challenge prior knowledge as well as understanding of the current topic.
The lesson begins with the introduction of the term genome and proteome and students are challenged to make the link between the genes in an organism and all of the proteins that can be produced by these sequence of bases. Moving forwards, students will learn that RNA is a member of the family of nucleic acids and therefore has a number of structural features that were previously seen in DNA. A quiz round called “A FAMILY AFFAIR” is used to challenge their knowledge of DNA to recognise those features that are also found on RNA such as the chain of linked nucleotides, pentose sugars, nitrogenous bases and phosphodiester bonds. The next task pushes them to consider features that have not been mentioned and therefore are differences as they answer a structured exam-style question on how RNA differs from DNA. Students will learn that RNA is shorter than DNA and this leads into the final part of the lesson where mRNA and tRNA are introduced and again they are challenged to use the new information explain the difference in size. Brief details of transcription and then translation are provided so that students are prepared for the upcoming lessons on protein synthesis.

Topic 4.2: DNA and protein synthesis (AQA A-level Biology)
Each of the 3 lessons in this bundle are fully-resourced and have been designed to cover the content as detailed in topic 4.2 (DNA and protein synthesis) of the AQA A-Level Biology specification. The specification points that are covered within these lessons include: * The concept of the genome and the proteome * The structure of mRNA * The structure of tRNA * Transcription as the production of mRNA from DNA * The differences between the outcome of transcription in porkaryotes and eukaryotes * Splicing * Translation as the production of polypeptides from the sequence of codons on mRNA The lessons have been written to include a wide range of activities and numerous understanding and prior knowledge checks so students can assess their progress against the current topic as well as be challenged to make links to other topics within this topic and earlier topics If you would like to see the quality of the lessons, download the structure of RNA lesson as this has been shared for free
