Biotechnology and Genetic Modification
What you'll learn
In this course students will learn exactly what they need to know for their Biology IGCSE exams. Students will learn about
1. State that bacteria are useful in biotechnology and genetic modification due to their rapid reproduction rate and their ability to make complex molecules
2. State that bacteria are useful in biotechnology and genetic modification due to their rapid reproduction rate and their ability to make complex molecules
(a) few ethical concerns over their manipulation and growth
(b) the presence of plasmids
3. Describe the role of anaerobic respiration in yeast during the production of ethanol for biofuels[/center]
4. Describe the role of anaerobic respiration in yeast during bread-making
5. Describe the use of pectinase in fruit juice production
6. Investigate and describe the use of biological washing powders that contain enzymes
7. Explain the use of lactase to produce lactosefree milk
8. Describe how fermenters can be used for the large-scale production of useful products by bacteria and fungi, including insulin, penicillin and mycoprotein
9. Describe and explain the conditions that need to be controlled in a fermenter, including: temperature, pH, oxygen, nutrient supply and waste products
10. Describe genetic modification as changing the genetic material of an organism by removing, changing or inserting individual genes
11. Outline the process of genetic modification using bacterial production of a human protein as an example, limited to
(a) isolation of the DNA making up a human gene using restriction enzymes, forming sticky ends
(b) cutting of bacterial plasmid DNA with the same restriction enzymes, forming complementary sticky ends
© insertion of human DNA into bacterial plasmid DNA using DNA ligase to form a recombinant plasmid
(d) insertion of recombinant plasmids into bacteria
(e) multiplication of bacteria containing recombinant plasmids
(f) expression in bacteria of the human gene to make the human protein
12. Outline examples of genetic modification
(a) the insertion of human genes into bacteria to produce human proteins
(b) the insertion of genes into crop plants to confer resistance to herbicides
© the insertion of genes into crop plants to confer resistance to insect pests
(d) the insertion of genes into crop plants to improve nutritional qualities
13. Discuss the advantages and disadvantages of genetically modifying crops, including soya, maize and rice
Requirements
Access to a device to watch lessons - phone, tablet, or computer No textbook needed - everything is covered in the course
Description
This Biology course is structured specifically around the latest Cambridge IGCSE and GCE Biology syllabus, ensuring complete and accurate coverage of every objective students need to master for their examinations. Students preparing for AP Biology, IB Biology, or equivalent international curricula will also find this course highly valuable for building a thorough understanding of the theory component of their exams, as the core biological concepts covered are closely aligned across these specifications.
The course focuses onUnit 21: Biotechnology and Genetic Modification, a fascinating and increasingly examined unit that brings together biology, technology and real-world applications in a way that examiners love to test across all papers. From the role of yeast in fermentation and bread-making to genetic modification of crops and the large-scale production of insulin - every syllabus objective is covered in full, with zero gaps.
Every syllabus objective is covered comprehensively, without overloading you with irrelevant material. The content is precise, focused, and directly aligned with what examiners expect - so you spend your time learning exactly what matters and nothing that does not. Throughout every lesson, real past paper questions are used to show you how this unit is examined, what a full-mark answer looks like, and the common mistakes that cost students marks every single year. You will know not just what to say, but how to say it - and equally importantly, what not to write.
The course builds strongexam technique alongside content knowledge, covering every question type across Papers 1, 2, 3 and 4 - from multiple choice and short answer to structured and extended response questions. Students leave this course knowing exactly how to approach any question on this unit regardless of how it is worded.
Every video lesson comes with adownloadable PDF resource that contains everything you need to know for that specific lesson - definitions, diagrams, key points and exam tips - all written and structured to match exactly what the syllabus requires. There is no need to open a textbook, search for revision guides, or look anything up online. Simply watch the lesson, download the PDF, study from it, and go straight to past papers. Everything you need is right here in one place.
Thepractical component is fully covered in this course. Students are taken through the investigation into the use of biological washing powders containing enzymes - exploring how biological detergents work, what conditions affect their performance, and how to design, carry out and evaluate this type of investigation. The experiment is broken down in full - covering the method, variables, expected results, data interpretation and evaluation - with specific training on how to answer practical questions inPapers 5 and 6 that test experimental skills, data analysis and scientific reasoning under exam conditions.
This course is ideal for students aiming for high achievement and A* grades in Biology examinations.
