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 […]
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, […]
Antigen presentation is a crucial process in the immune system. Immune cells, like dendritic cells, display fragments of pathogens (antigens) on their surfaces to activate T cells. This interaction triggers adaptive immune responses, aiding in pathogen elimination and the creation of immunological memory for future protection. This is an MCQ […]
Adaptive immunity is a sophisticated defines mechanism in organisms, including humans. It involves the recognition of specific pathogens by immune cells, such as T and B cells, leading to targeted responses that create memory for future encounters, enabling faster and more effective immune reactions. This is an MCQ on Adaptive […]
