DNA sequencing is a method used to determine the precise order of nucleotides within a DNA molecule. This process is crucial for understanding genetic information and can help identify genetic disorders, track diseases, and advance personalized medicine. By analyzing the sequence of nucleotides, scientists can gain insights into the genetic blueprint of organisms. There are several techniques for DNA sequencing, including Sanger sequencing and next-generation sequencing (NGS). These methods have revolutionized genomics by allowing rapid and cost-effective sequencing of entire genomes. As a result, DNA sequencing plays a vital role in research, diagnostics, and biotechnology applications.
