MCQ on Cellulose Synthesis in Plants: Cellulose is a carbohydrate (polysaccharide) composed of glucose molecules, serving as a structural component in plant cell walls. Cellulose biosynthesis in plants primarily occurs in the plasma membrane, where cellulose synthase enzymes (CESA) assemble glucose molecules into cellulose chains. These chains then form microfibrils, providing structural integrity to plant … Read more
MCQ on Electron Transport System: The electron transport system, or electron transport chain (ETC), is a series of protein complexes in the inner mitochondrial membrane or thylakoid membrane in chloroplasts. It transfers electrons, generated during cellular respiration or photosynthesis, to generate ATP, a crucial energy currency, by harnessing electron flow for proton pumping and chemiosmotic … Read more
MCQ on PCR and its Applications: PCR (Polymerase Chain Reaction) is a molecular biology technique used to amplify DNA segments exponentially. It involves cycles of heating and cooling to replicate a target DNA region, making it a valuable tool in DNA analysis, genetic research, and diagnostics, allowing the detection of specific sequences. This MCQ will … Read more
MCQ on SDS PAGE: SDS-PAGE (Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis) is a widely used laboratory technique to separate proteins based on their size. It involves denaturing proteins with SDS and then subjecting them to electrophoresis through a polyacrylamide gel, enabling accurate molecular weight determination and protein analysis. This MCQ will help you to understand … Read more
