Microbiology - MCQ Practice Questions
Microbiology sits behind a lot of applied biology, so the fundamentals here carry into medicine, food technology and biotechnology alike. Practice covers bacterial structure and growth, viruses, fungi and parasites, sterilisation and culture techniques, immunology, and microbial genetics. Technique based questions explain the purpose of each step, because that is usually what separates a memorised protocol from a usable one.
