This BIOL 271 Microbiology Module 1 2026/2027 study guide contains 79 questions and answers covering the foundational concepts of microbiology, cell biology and biological macromolecules. The 14-page resource begins with microbes, pathogens, microbiology, the central dogma of biology and cellular organization before comparing prokaryotic and eukaryotic cells, bacteria, archaea, viruses, Animalia, Plantae, Fungi and Protista. It then develops the structural and molecular foundations needed for later microbiology modules.
The cell biology section provides focused revision of cell membranes, phospholipid bilayers, cell walls, cell envelopes, peptidoglycan, glycocalyx, cytoplasm and cytosol. Students also review major eukaryotic organelles and their functions, including the nucleus, nucleolus, ribosomes, rough and smooth endoplasmic reticulum, Golgi complex, lysosomes, mitochondria, chloroplasts and centrioles. The material distinguishes cell-wall composition among bacteria, archaea, plants, fungi, yeast and diatoms while also reviewing common bacterial morphologies such as cocci, bacilli, spirilla and vibrios.
The molecular biology portion covers monomers, polymers, proteins, amino acids, nucleic acids, DNA, RNA, nucleotides, genes and protein synthesis. It reviews DNA-to-RNA-to-protein information flow, purines and pyrimidines, complementary base pairing, DNA versus RNA structure and cellular locations of nucleic acids. The final sections address the four major classes of biological macromolecules, with detailed material on lipids, phospholipids, triglycerides, steroids, saturated and unsaturated fats, carbohydrates, monosaccharides, disaccharides and polysaccharides.
The document's course identifier and 2026 content align closely with the current Portage Learning BIOL 271 Microbiology with Lab syllabus, which describes BIOL 271 as a four-credit systematic examination of the microbial world with particular emphasis on pathogens, including microbial morphology, physiology, genetics, metabolism and enzymatic reactions. Portage Learning states that its college courses are offered through Geneva College and Bushnell University, with the transcript-issuing institution depending on the student's state of residence.
Relevant Students: This document is particularly relevant for BIOL 271 students, Portage Learning Microbiology students, Geneva College and Bushnell University students completing Portage-delivered coursework, pre-nursing and nursing students, allied health students, pre-health students, biology students, and learners completing microbiology prerequisites for healthcare programs. It is especially useful for students beginning Module 1 who need concentrated revision of microbial classification, cellular structure, organelles, membranes, DNA/RNA, protein synthesis and biological macromolecules.

The official 2026 syllabus identifies general biology and chemistry as prerequisites and describes BIOL 271 as a continuously offered four-credit microbiology course. Portage Learning further explains that its courses are delivered through its online platform while college credit is issued through its accredited partner institutions, Geneva College and Bushnell University.
