RAPD Technique Explained | Random Amplified Polymorphic DNA | Principle, Steps & Applications

Random Amplified Polymorphic DNA (RAPD) is a PCR-based molecular marker technique used to detect genetic variation in DNA sequences. In this video, we explain the principle, procedure, and applications of the RAPD technique in an easy and clear way. RAPD uses short random primers in PCR to amplify different segments of genomic DNA, producing unique banding patterns that help identify polymorphisms among organisms. This method is widely used in genetic mapping, biodiversity studies, plant breeding, species identification, and evolutionary research. The lecture is helpful for students of biotechnology, microbiology, genetics, and life sciences who want to understand molecular marker techniques used in DNA analysis. Diagrams and simple explanations are included to make the concept easy to understand.
