MCQ on Cell Signalling in Plants: In plants, cell signalling occurs through various mechanisms, including phytohormones like auxins, cytokinins, and gibberellins. These molecules regulate growth, development, and responses to environmental cues by binding to receptors and initiating intracellular pathways, ensuring coordinated physiological processes.

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, […]
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 […]
MCQ on Blotting Techniques: Blotting is a laboratory technique used to transfer molecules, typically DNA, RNA, or proteins, from a gel matrix (such as agarose or polyacrylamide gel) to a solid membrane. This technique allows for the detection, identification, and analysis of specific molecules through various assays like Southern, Northern, […]
Studying protein structure is crucial for understanding their functions, interactions, and roles in biological processes. It aids in drug design, predicting protein behaviour, and addressing diseases caused by misfolding. Knowledge of structure enables targeted interventions, rational engineering of enzymes, and advances in fields like biotechnology, medicine, and biochemistry. Please use […]
