PowerPoint about the polymerase chain reaction. Includes a video showing the shedding of skin cells, an animation to show the molecular processes of PCR and then includes a few activities for students to complete. Where possible, there are links to previously taught material. The PPT contains (a few) notes with questions and answers. This resource is designed to be used with the class notes for this topic.

Detailed PowerPoint containing a starter question before insertion, transformation and the identification of the desired gene/protein are outlined. Where possible, there are links to previously taught material. The PPT contains (a few) notes with questions and answers. This resource has taken a long time to perfect (hence the price) and is designed to be used with the class notes for this topic.

PowerPoint introducing the topic. Contains a starter question and a quick video, with one of my favourite quotes, before using the manufacture of synthetic insulin as an example to illustrate where this field of DNA technology originated. it outlines the different steps involved in the topic for the isolation, replication and identification of the desired gene/protein, and then introduces stick and blunt ends. Where possible, there are links to previously taught material. The PPT contains (a few) notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

Topic overview check sheet for use when peer-marking student overview of this topic. I give these out and usually give my classes a week to hand write their notes (unless they have access to word processor in examinations) and complete the exam style questions from the text book.

Class notes to accompany the PowerPoints available on TES for this topic. These will save you hours and hours and hours of preparation! Contains gap fill paragraphs, questions, images for students to label, past exam questions and more. Marking guidelines also included.

PowerPoint on selection at AS level, Includes an introduction to the work of Florey, Chain and Heatley on the development of penicillin and links this to (earlier year 1 material about) prokaryotes. There's a card sort activity, which students match up with numbers associated with images of antibiotic resistance which is used to and illustrate directional selection. Stabilising selection is exemplified by human birth weights. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic. There's also a very quick meiosis quiz included for a recap.

PowerPoint introducing Adaptation and introducing a key component of natural selection. Contains a quick quiz to begin on cell division and then a card sort to consider reproductive success and allele frequency. Not my finest work, hence the price, but offered her primarily to accompany the class notes and to be included / available as part of the topic bundle.

A lot of work has gone into this, hence the price! PowerPoint detailing meiosis along with a few card sort activities. Although students do not need to know the stages of meiosis, I use this an an opportunity to recap mitosis and to think about the differences between mitosis and meiosis, and the differences between meiosis 1 and meiosis 2. I have the cards printed on different colours, corresponding to those on the PPT background for meiosis 1 & 2. Crssing over and independent segregation are also detailed with animations and non-disjunction is also considered. There's 10 questions near the end of the PPT, which are on the worksheet for this lesson (available separately on TES), but the answers are provided here. Where possible, there are links to previously taught year 1 material (i.e. mitosis, DNA, haploid, diploid terminology, etc). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint introducing the topic and detailing gene mutations at AS level. Contains a few chances for students to use the codon table to identify the amino acid sequences. Sickle cell anaemia is used as an example of a genetic mutation and where possible, there are links to previously taught year 1 material (i.e. drawing a labelled amino acid). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint detailing translation, with a card sort activity that students can use to learn the process, but also figure out the missing words. Also included is a student version you can upload to your VLE, which doesn't contain all the answers. There's a quick quiz to recap the structures of DNA, tRNA and mRNA and a recap on transcription and splicing. There's short animation to show translation, but this does include the presence of a release factor (which is not in the spec). Also, it contains information about amino acid activation, which you can of course remove if you would like. Where possible, there are links to previously taught year 1 material (i.e. drawing a labelled amino acid). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint detailing transcription and splicing. Also included is a student version you can upload to your VLE, which doesn't contain all the answers. There's an introduction to transcription and translation, focusing on the locations where these occur and then a few short animations to show transcription. Where possible, there are links to previously taught year 1 material (i.e. drawing a labelled amino acid). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint detailing the structure of mRNA and tRNA. Really focuses on the correct use of terminology in this lesson, and the students ability to use the codon table. There's a short quiz at the end. Where possible, there are links to previously taught year 1 material. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint reviewing the basics of DNA, and what is a gene. Then goes on to the triplet code and introduces the terms, degenerate, non-overlapping and universal. It then goes on to consider how we understand it is a triplet code, and not a singlet or doublet code. It also requires students to use the codon table and gets them to think about using the complement of the DNA nucleotides (in mRNA) to determine the amino acid sequence. This also has a video embedded which answers the question - what percentage of the human genome are introns? Where possible, there are links to previously taught year 1 material. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint reviewing the basics of DNA, how it differs between prokaryotic and eukaryotic cells, the structure of a chromosome (unpicking the differences between chromosomes and chromatids), haploid/diploid terminology and what homologous chromosomes are. Where possible, there are links to previously taught year 1 material. This also has a video embedded which introduces the fateful encounter hypothesis, but then uses the video to ask the students to think about the structure of mitochondrial DNA. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.
