Used extensively in molecular biology research for studying DNA structure, function, and interactions. It serves as a template for PCR amplification, DNA sequencing, and cloning experiments. Also employed in hybridization techniques like Southern blotting to detect specific DNA sequences. Acts as a substrate for enzymes such as DNA polymerases, ligases, and restriction endonucleases. Utilized in biotechnological applications for genetic engineering and recombinant DNA technology. Applied in diagnostic assays for detecting genetic disorders and infectious diseases. Plays a role in forensic science for DNA fingerprinting and identity verification. Used in educational settings for teaching DNA extraction, purification, and analysis techniques.
