Next-generation sequencing (NGS) is a modern method used to determine the sequence of DNA or RNA in a sample. Unlike traditional sequencing techniques, NGS can analyze millions of fragments simultaneously, making it faster and more cost-effective. This technology is widely used in various fields, including genomics, personalized medicine, and cancer research. NGS allows researchers to identify genetic variations, study gene expression, and explore complex biological systems. By providing comprehensive data, it helps scientists understand diseases better and develop targeted therapies. The ability to sequence entire genomes quickly has revolutionized the way we approach genetic research and diagnostics.
