Every gene is a section of DNA that contains instructions for making a protein. For example, the insulin gene contains instructions for making the insulin protein, which helps control blood glucose concentration.
Step-by-step lessons covering Edexcel IGCSE Biology Genetic modification (genetic engineering) for IGCSE Biology. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Start with the foundational cell biology and core content before moving on to the more data-heavy ecology, genetics and practical-skills topics, which carry a large share of the exam marks.
