A PowerPoint which explores how DNA Methylation of promotors and Acetylation of histones affects gene expression. It is well illustrated and explores its implications in genetic disorders (prader-willi and angelman) as well as cancer. The worksheet then explores these concepts, which have suggested answers provided via the markscheme.

Cut and stick activity and follow-up questions on in vivo gene cloning (DNA Technology) on a double-sided file. Covers the process including: restriction enzymes, DNA ligase, marker genes, replica plating, antibiotic resistance and GFP Looks really nice if done on full colour (just don’t tell your HoD!) and full markschemes are included for the cut and stick ordering activity as well as the follow-up questions

***Get 90% off the cost of your first resource worth up to £10 with code JANUARY90. New buyers only!*** Double sided A level worksheet on ATP and its uses. It has a particular focus on signalling pathways and cancer. Answers are included as well as a simple presentation to cover the key features of ATP

GCSE Biology - Protein Synthesis mechanism presentation which can be used to walk through protein synthesis with your GCSE classes. Covers, transcription, translation and the triplet code (although doesn’t explicitly refer to them as transcription and translation!) ***Not suitable for Edexcel exam board as there is no mention of tRNA

Autosomal Linkage and Chi-Squared A Level Biology PowerPoint Presentation - 11 slides long. It is a comprehensive Powerpoint with useful animations which I have used many times to successfully walk my A level students through autosomal linkage. Most of the slides have information in the 'notes' section to help guide you through each slide. Covers the following: Why drosophila are used as a model organism Chi-squared in genetics Autosomal linkage How linkage is used in mapping

GCSE blood components task - cut and stick activity for students to link function to the components of the blood. There are extension questions below the table and projectable answers too on a PowerPoint file

A short animated presentation to discuss how siRNA works to prevent translation of mRNA and potential applications.

A single sided worksheet to guide students through the use of standard deviation when analysing and comparing data. It does not go over the calculation. Markscheme included

A fun and engaging relay quiz which could be done in groups of 1-3 which covers maths skills related to enzymes, cells, heart, ecology and exchange. The maths skills covered are %, uncertainty, volumes, rate calculations, stats, sig figs to name a few. Takes about 30 minutes and provides an excellent opportunity for AfL . INSTRUCTIONS are included in the notes section of the markscheme

A Simple presentation which includes a starter to recap the structure of the heart, and then promote discussion and to how coronary arteries may become blocked, risk factors and treatments for CHD. The powerpoint has supporting notes. The two sided worksheet includes low to higher demand questions to check understanding of CHD progression, risk factors and treatments. The dominoes are a nice pairs/individual loop activity which could be used as a starter to review heart structure and blood components

A level Biology maths skills worksheet. Single sided and answers included. Looks at percentages and percentage change calculations and using graphs. All under the context of lipids

A three-sided worksheet that covers gene probes and genetic tests. It is specifically aimed for the AQA A level Biology spec, but will be appropriate for most exam boards. It assesses student understanding of some core principles, whilst running through how geentic tests are carried out for cystic fibrosis, huntington’s and digeorge syndrome (using chromsomal micro-array). Comprehensive and projectable markscheme included

A Level Biology Maths Skills - Revision - Solutions and Dilutions A worksheet based activity consisting of 2 sides This worksheet explores volume conversions, calculating how much mass of a substance is required to make up a particular concentration, how to dilute a stock solution, and how to perform serial dilutions. The second side is exam style questions. Markscheme included - handwritten as the working out is all fully shown

Four worksheets that I have recently written in order to update some old resources that I was using. They are aimed at the Genetic Diversity 3.4 AQA topic. Suggested Answers provided for all The Genetic Code (2 sided) Splicing Mutations (AS) Classification and species

Four worksheets that I have recently written in order to update some old resources that I was using. They are aimed at the Cells 3.2 AQA topic. Suggested Answers provided for all Cells and Mitosis recall worksheet (2 sided) Antibody structure and function HIV ELISA tests

A revision sheet for the AQA GCSE Biology topic ‘Studying Cells’. This is a visual sheet with various questions, colouring activities and CLOZE tasks. It gives an overview of the whole of the topics- cell structure, magnification, mitosis and the cell cycle, stem cells and transport across membranes. I have produced this with my foundation students in mind, who are perhaps lacking motivation with the exam season fast approaching. There is a set of dominoes included which contain 15 dominoes which students can cut out to form a loop of Q&A for the cells topic. the formatting of these dominoes looks wring on the preview but I can assure you it is fine when you download then

***Get 90% off the cost of your first resource worth up to £10 with code JANUARY90. New buyers only!*** A level Biology double-sided worksheet looking at the genetic code. This sheet has been produced with the AQA spec in mind but would be highly relevant to any A level Biology course. It touches on introns and exons, how to read a triplet table and the nature of the genetic code being Universal, Non-overlapping and Degenerate, whilst recapping some of the basics on nucleotides and amino acids. Also included is a comprehensive markscheme which you could scroll through via a projector to review with your class.

***Get 90% off the cost of your first resource worth up to £10 with code JANUARY90. New buyers only!*** Engaging activity on DNA replication - students work through the sheet using pipe cleaners to explain why the evidence proves replication is semi-conservative and not conservative or dispersive. Focusses on the experiment involving bacteria grown on heavy and light N isotopes. All you will need are 2 pipe cleaners of one colour, and 14 of another colour, per group (cut them into shorter ones to make them go further!). It is a student led activity - the presentation is a markscheme which allows you to work through the correct answers via useful PowerPoint animations

This is a work sheet on Maths skills for Biologists, which focusses on Logarithms and guides students through how to use their calculator to work out log calculations. It includes a comprehensive markscheme. The seconds side just includes a PPQ involving natural logs from a past paper.
