Twenty original four-option questions assess Topic 21 Biotechnology and genetic modification, including the usefulness of bacteria, yeast fermentation, pectinase, biological washing powders, lactase, fermenter control, recombinant DNA techniques and genetically modified crops. Twelve black-and-white figures and data displays support interpretation, application and problem-solving. Each item has one intended best answer. Questions are independently written; Cambridge past papers and specimen materials are used only to guide assessed skills and style.
Twenty original four-option questions assess Topic 21 Biotechnology and genetic modification, including the usefulness of bacteria, yeast fermentation, pectinase, biological washing powders, lactase, fermenter control, recombinant DNA techniques and genetically modified crops. Twelve high-contrast black-and-white figures and data displays support interpretation, application and problem-solving. Each item has one intended best answer. Questions are independently written; Cambridge past papers and specimen materials are used only to guide assessed skills and style. Figure labels are neutral and do not identify or highlight the correct option.
