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, […]
The ABC model of flower development is a genetic framework that explains how specific genes control the formation of floral organs in plants. It consists of three classes of genes: A (for sepals and petals), B (for petals and stamens), and C (for stamens and carpels). Combinations of these genes’ […]
Transposons, also known as “jumping genes,” are DNA sequences in the genome that can move or “transpose” to different locations within the genome. They can disrupt genes, cause mutations, or regulate gene expression. Transposons play a role in evolution and genetic diversity but can also lead to genetic disorders if […]
