This is an engaging and fully-resourced revision lesson which uses a range of exam questions, understanding checks, quick tasks and quiz competitions to enable students to assess their understanding of the content within topic 3 (Genetics) of the Edexcel GCSE Biology 9-1 specification.
The specification points that are covered in this revision lesson include:
- Explain some of the advantages and disadvantages of asexual reproduction, including the lack of need to find a mate, a rapid reproductive cycle, but no variation in the population
- Explain some of the advantages and disadvantages of sexual reproduction, including variation in the population, but the requirement to find a mate
- Explain the role of meiotic cell division, including the production of four daughter cells, each with half the number of chromosomes, and that this results in the formation of genetically different haploid gametes
- Describe the structure of DNA
- Describe the genome as the entire DNA of an organism and a gene as a section of a DNA molecule that codes for a specific protein
- Explain how the order of bases in a section of DNA decides the order of amino acids in the protein and that these fold to produce specifically shaped proteins such as enzymes
- Describe the stages of protein synthesis, including transcription and translation
- Describe how genetic variants in the coding DNA of a gene can affect phenotype by altering the sequence of amino acids and therefore the activity of the protein produced
- Explain why there are differences in the inherited characteristics as a result of alleles
- Explain the terms: chromosome, gene, allele, dominant, recessive, homozygous, heterozygous, genotype, phenotype, gamete and zygote
- Explain monohybrid inheritance using genetic diagrams, Punnett squares and family pedigrees
- Describe how the sex of offspring is determined at fertilisation, using genetic diagrams
- Calculate and analyse outcomes (using probabilities, ratios and percentages) from monohybrid crosses and pedigree analysis for dominant and recessive traits
- Explain how sex-linked genetic disorders are inherited
- State that most genetic mutations have no effect on the phenotype
The students will thoroughly enjoy the range of activities, which include quiz competitions such as “Is this SYNTHESISED correctly” where they have to recognise whether a passage on protein synthesis is 100% correct or contains errors whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams.

Fantastically designed, goes through the most difficult parts of the topic with engaging activities. Thank you so much for making this available for free.
Very useful, interesting resource. Thank you.
I ran a drop down GCSE Biology revision day for our year 11s. Using the revision lessons available from GJH Education as part of the learning and activities was very effective. Every one of the 90 pupils that attended engaged very well with the material and enjoyed them too (which was a bonus!). Much of the feedback that I received was about how they didn't realise that they were learning because it was fun. The brilliant thing is that they were able to retrieve what they had learnt that day a few weeks later. Fabulous, well thought out resources that are A*, many thanks!
This was used when I covered a science lesson at short notice: it was immensely helpful, easy to use and and understand, went down well with the students. Thank you.<br />
